Headlights and tail lights are the only source of vision for drivers while driving at night. Even if the street or road lights are on, headlights and tail lights play a significant role in safe driving. One of the recurring issues that vehicles face is moisture in headlights and tail lights, this issue hinders the night-time vision of the vehicles. Moisture also hinders potency and serviceable life of the headlights and tail lights.
If you are facing such issues, you could use the following steps to help yourself out.
Headlights
Step-1 Unmount the headlight assembly
Before anything, disconnect the vehicle’s battery by disconnecting its cables. To unmount the headlight assembly, you would require a socket and a ratchet. To wrench the screws out, use a ratchet. Reading the car manual should suffice.
Step-2 Clean up the moisture or humidity
You should use a lint-free cloth for this job. Wipe off the moisture throughout the headlight assembly. Do check the area near the light and the corners. Don’t wipe hard as it could cause cracks in the glass and those draw more humidity in.
Step-3 Stick the Silica Gel packs in
After removing all the moisture with the lint-free cloth, put Silica Gel packs in. Silica Gel is an easy and long-term solution for moisture inside the headlight assembly as it thoroughly absorbs the moisture present around it. Make sure you stick these gel packs with the tape to keep them static, so that they don’t come in the way of light.
Step-4 Apply fresh headlight sealants
This step entirely depends on the frequency of the issue of moisture you are facing. You can go ahead with this procedure if you frequently face moisture accumulation in your headlights. Remove the mask of the headlight, take some sealant (sufficient to cover the area of the frame), apply the sealant on the frame gently, put the mask over the headlight back, and compress to make them stick properly.
Step-5 Re-mount the headlight
Fit the headlight where you took it out from. All you need to do is, insert the screws back, wrench them adequately with the ratchet.
This may sound surprising but your car’s lights do need some moisture, usually, they have holes to blow out the heat produced by the light. Thoroughly compact headlights could implode eventually.
Tail lights
Step-1 Unmount the tail light
Disconnect the vehicle’s battery by disconnecting its cables. Use a ratchet to wrench out the screws and bolts right behind the tail light. If you are unable to do this, use the vehicle’s manual. Cautiously pull the tail light assembly off the vehicle.
Step-2 Detach the bulb and drain out the water
There is a big circular screw or cap mounted at the backside of the light’s assembly, it’s called Rubber Housing Seal Cap. Rotate the cap counterclockwise by your hand, it will loosen up. Carefully pull the cap along with the bulb right out of the assembly. Flip the housing to drain out the excess water.
Step-3 Carve and hole in cardboard box big enough to fix the hair dryer nozzle
To dry out the light housing, it needs to be kept in a mildly heated atmosphere. You could make such an arrangement with the help of a cardboard box. Take a cardboard box, aim a hairdryer nozzle on it, touch the nozzle to any of the walls of the cardboard, mark an outline around the nozzle and carve the cardboard on the outline with any knife or cutter. Make sure the nozzle fits in the cut-out hole tightly to avoid any heat escape.
Step-4 Keep the tail light across from the hole
Put the tail light in the cardboard box, position it across from the hole carved in a way that the hole in cardboard faces the bulb hole in the housing.
Step-5 Place a piece of cardboard amid the carved hole and the taillight
Direct exposure to heat could hamper the taillight, this is why you need to put a piece of cardboard between the hole carved for the hair dryer nozzle and the tail light. Keep the piece standing upright.
Step-6 Fix the nozzle in the hole and start the dryer at the minimum heat
Carefully insert the nozzle of the hairdryer in the hole. Close the box as compactly as you could, set the dryer at the minimum heat and start. Leave it on for around 5 minutes and check if the tail light has dried completely, if not, repeat for another 5 minutes.
Step-7 Take out the dried tail light and re-mount it in the vehicle
Carefully pick the tail light housing as it would be considerably hot, you should use a glove while holding it. And then mount it back to the vehicle using a ratchet or a screwdriver.
An easier option could be using a hair dryer directly on the headlights and tail lights, but direct heat could damage the set-up.
FAQs
Q. How do I know if my car's rear lights are suffering from moisture?
Keep an eye out for a hazy or foggy look in your car tail lights. If you spot any water droplets, it’s time to roll up your sleeves and tackle the issue before it impacts your visibility on the road.
Q. Is it safe to drive with moisture in the car headlamp?
Not at all! Moisture in your car headlights can dim their brightness, which could lead to dangerous situations while driving at night. It is better to deal with it now than put your life, and also that of others, at the risk of a mishap later.
Q. What steps can I take to prevent moisture in my car headlights?
Regular inspections of your seals are crucial to prevent moisture in car headlamps. Consider tossing a few silica gel packs inside the headlight assembly. They’re extremely efficient at absorbing moisture and keeping confined areas dry.
Q. Can I use a hair dryer directly on my car taillights to dry them out?
While a hair dryer sounds tempting, be cautious! Direct heat can cause damage to car tail lights. Instead, create a makeshift drying station with cardboard to help evenly distribute the warmth and keep your lights safe.
Q. What causes moisture problems in car rear lights?
It’s a classic case of nature’s trickery! Temperature fluctuations lead to condensation inside your car tail lights and car headlights. If the seals aren’t up to par, moisture can sneak in and wreak havoc. Keeping those seals intact is key!
