Tail lights make a vehicle visible to other drivers in low-light conditions. While they’re designed to be durable, any water pooling inside the covers could eventually compromise the lighting’s electrical system. While used tail lights are convenient and affordable replacements, you may simply need to replace the cover to protect the lamp. The guide below covers all you need to know to restore the affected fixture's appearance and functionality.

Why Is There Water in Your Car’s Tail Light?

Rainwater can enter the cover through cracks. Examine the surface for fissures or deep scratches that might allow moisture through. If you aren’t sure, shine a flashlight into the light. Check around the assembly's perimeter, as the seal between the outer and inner components can wear down and create gaps.

Then, open the trunk to check the rubber grommets along the opening of the area. In addition to dampening the sound of the trunk when it closes, the grommets keep water out, preventing it from accumulating around the sides of the tail lights. Worn grommets make water more likely to seep through cracks.

What Are the Solutions?

If the fixture’s cover has scratches or cracks, replace it. Replacing it as soon as possible prevents water from affecting the lamp, potentially saving you from a ticket for a failed light.

If you want to replace the cover on your own, start by disconnecting the car’s battery to prevent power from reaching the system. Next, follow the steps outlined in the vehicle’s manual to remove the cover. The manual might instruct you to use a needle nose plier to remove the clips holding the light to the car. Alternatively, unscrew any bolts with a wrench. Afterward, you should be able to remove the light by pulling it gently with two hands.

Once the attachment is off, dry the system and install a replacement tail light by reversing the removal instructions.
