How To Dry Tail Lights A Comprehensive Guide
Hey guys! Ever notice how sometimes your car's tail lights look like they're crying, with condensation or water droplets trapped inside? It's a common issue, especially on humid days or after a heavy rain. When you are running your vehicle's lights, the air in your tail lights heats up and gets trapped inside the plastic housings. Once the outside air cools down, the moisture condenses into water droplets inside your lights. Not only does it look bad, but it can also potentially damage the electrical components and reduce the effectiveness of your lights. But don't worry, drying out your tail lights is a pretty straightforward process you can tackle yourself. Let's dive into why this happens and, more importantly, how to fix it!
Why Do Tail Lights Get Moisture Inside?
Okay, so before we get into how to dry out your tail lights, let's quickly chat about why this happens in the first place. Understanding the cause can help you prevent it from happening again. The primary culprit here is condensation. Just like a cold glass of water on a hot day, the temperature difference between the inside and outside of your tail light housing causes moisture in the air to condense into water droplets. This often happens when you're running your lights, which heat up the air inside the housing. Then, when you turn them off and the outside air cools down, that warm, moist air inside turns into condensation.
Another common reason is leaks. Over time, the seals around your tail lights can degrade or become damaged, allowing water to seep inside. This can be due to age, weather exposure, or even minor impacts. Even a tiny crack or a loose seal can let moisture in. Think of it like a tiny hole in a boat – water will eventually find its way in! Furthermore, if your tail light housing has any venting issues, it can trap moisture inside. Many tail light assemblies have small vents designed to allow air to circulate and prevent condensation. If these vents are blocked by debris or damaged, moisture can build up inside. So, condensation, leaks, and blocked vents are the main reasons your tail lights might be looking a bit teary-eyed. Now that we know why, let's get to the how!
Methods to Dry Out Your Tail Lights
Alright, let's get to the nitty-gritty – the actual methods for drying out those pesky tail lights. There are several ways you can tackle this, ranging from simple DIY solutions to slightly more involved approaches. We'll start with the easiest ones and then move on to the more complex methods. Remember, safety first! Always disconnect your car's battery before working on any electrical components, and be careful when handling tools and hot air.
1. The Sun and Air Method
This is the simplest and often the most effective method, especially if the condensation isn't too severe. It relies on good old-fashioned sunlight and air circulation. To start, park your car in a sunny spot. The sun's warmth will naturally help to evaporate the moisture inside the tail light housing. Next, and this is crucial, remove the tail light assembly from your car. This allows for better air circulation and speeds up the drying process. Check your car's owner's manual for specific instructions on how to remove your tail lights, as the process can vary slightly depending on the make and model. Once the assembly is removed, carefully remove the bulbs from the housing. This opens up the housing and allows air to flow freely through it. Place the tail light assembly in a well-ventilated area, preferably in direct sunlight, for several hours. The amount of time needed will depend on the humidity and the amount of moisture inside, but generally, a full day in the sun should do the trick. Periodically check the tail light to see if the moisture has evaporated. Once it's completely dry, reassemble the bulbs, reinstall the tail light assembly back onto your car, and you're good to go! This method is gentle, natural, and doesn't involve any special tools or equipment. It's always a great first step to try.
2. Using a Hair Dryer
If the sun isn't cooperating or you need a faster solution, a hair dryer can be your best friend. This method uses warm air to speed up the evaporation process. First, just like with the sun method, remove the tail light assembly from your car and take out the bulbs. This is crucial to ensure proper airflow and prevent any potential damage to the bulbs from the heat. Next, set your hair dryer to a low or medium heat setting. Never use the highest setting, as excessive heat can melt or warp the plastic housing of your tail light. Hold the hair dryer about 6-12 inches away from the tail light housing and gently blow warm air into the openings where the bulbs were. Move the hair dryer around to ensure even heating and prevent any one area from getting too hot. Keep the hair dryer moving and avoid focusing on one spot for too long. This will help to distribute the heat evenly and prevent damage. Periodically check the inside of the tail light housing to see if the moisture is evaporating. You might need to repeat this process several times, depending on the amount of moisture. Be patient and take breaks as needed to prevent the hair dryer from overheating. Once the tail light is completely dry, let it cool down before reassembling the bulbs and reinstalling the assembly back onto your car. Using a hair dryer is a quicker method than relying on the sun, but it's essential to use caution and avoid excessive heat to prevent any damage.
3. Silica Gel Packs
This method is a bit more passive but can be very effective, especially for persistent moisture issues. Silica gel packs are those little packets you often find in new electronics or clothing items – they're excellent at absorbing moisture. To use this method, remove the tail light assembly and the bulbs, just like with the previous methods. Then, place several silica gel packs inside the tail light housing. The number of packs you'll need will depend on the size of the housing and the amount of moisture present, but generally, 3-5 packs should do the trick. Seal the openings of the tail light housing with tape or plastic wrap to prevent air from getting in and out. This helps to concentrate the moisture absorption process. Leave the silica gel packs inside the tail light housing for at least 24-48 hours, or even longer if the condensation is severe. The silica gel will gradually absorb the moisture from the air inside the housing. After the waiting period, check the tail light to see if the moisture has disappeared. If necessary, you can replace the silica gel packs with fresh ones and repeat the process. Once the tail light is dry, remove the silica gel packs, reassemble the bulbs, and reinstall the tail light assembly back onto your car. This method is particularly useful for removing residual moisture and can be used in conjunction with other drying methods for best results. Plus, it's a great way to repurpose those silica gel packs you might otherwise throw away!
4. Drilling a Small Drain Hole (As a Last Resort)
Okay, this method should really be considered a last resort because it involves modifying your tail light housing. However, if you've tried everything else and the moisture keeps coming back, drilling a small drain hole might be the only way to permanently solve the problem. Before you even think about drilling, make absolutely sure that you've identified the source of the moisture and tried all other methods. Drilling a hole can introduce new problems if not done carefully. If you're confident that this is the right solution for you, choose a discreet spot on the bottom of the tail light housing where the hole won't be visible. Use a small drill bit – we're talking tiny, like 1/8 inch or smaller. You just want a small opening for water to drain, not a gaping hole. Carefully drill a hole through the plastic housing. Be gentle and avoid applying too much pressure, as this could crack the plastic. Once the hole is drilled, test it by pouring a small amount of water into the tail light housing and making sure it drains out. If the water drains properly, you're good to go. If not, you might need to slightly enlarge the hole, but again, keep it as small as possible. After drilling, consider sealing the edges of the hole with silicone sealant to prevent further cracking or water intrusion. Reassemble the bulbs and reinstall the tail light assembly back onto your car. Keep in mind that drilling a hole can potentially affect the resale value of your car and might not be legal in all jurisdictions, so be sure to check your local regulations before proceeding. This method should only be used when all other options have been exhausted.
Preventing Moisture Buildup in the Future
Now that you've successfully dried out your tail lights, let's talk about how to prevent moisture from building up again in the future. Prevention is always better than cure, right? There are several steps you can take to keep your tail lights clear and dry. The first and most crucial step is to check and replace the seals. As we discussed earlier, damaged or worn-out seals are a common cause of moisture intrusion. Inspect the seals around your tail lights for any cracks, gaps, or signs of deterioration. If you notice any issues, replace the seals as soon as possible. You can usually find replacement seals at your local auto parts store or online. Another important step is to inspect and clean the vents. Many tail light assemblies have small vents designed to allow air circulation. Make sure these vents are clear of any debris, dirt, or obstructions. You can use a small brush or compressed air to clean them out. If the vents are blocked, moisture can get trapped inside the housing. Additionally, consider using water-repellent sealant. Applying a water-repellent sealant around the edges of your tail lights can help to create an extra barrier against moisture. This is especially useful if you live in a rainy or humid climate. You can find water-repellent sealants specifically designed for automotive use at most auto parts stores. Regularly check your tail lights for any signs of condensation. Catching the problem early can prevent it from becoming a major issue. If you notice any moisture buildup, address it promptly using one of the drying methods we discussed earlier. Finally, avoid using high-pressure car washes directly on your tail lights. The high pressure can force water past the seals and into the housing. Instead, use a gentler washing method or hand-wash your car. By taking these preventative measures, you can keep your tail lights dry and clear, ensuring optimal visibility and prolonging the life of your lights.
When to Seek Professional Help
While drying out your tail lights is often a DIY-friendly task, there are situations where it's best to call in the professionals.
