Why is there moisture/condensation in your turn signal lights?
Moisture inside your car’s front or rear indicators / turn signal lights can be a frustrating problem to deal with. This is because it affects the amount of light that can be seen, leading to a potential failure of your Warrant of Fitness as well as safety issues. Moisture inside your car’s indicator lights can also lead to corrosion of components, resulting in the bulb and/or other parts needing replacement.

There are several things that can cause moisture to accumulate inside your car’s turn signal lights. These include:
- Weather and temperature changes: Rapid shifts in temperature or exposure to extreme weather conditions can cause moisture to accumulate inside the turn signal lights. Temperature variations can create a difference in air pressure, leading to condensation.
- Damaged or deteriorated seals: Over time, the seals that keep the turn signal light assembly watertight can degrade or become damaged. Cracked or worn-out seals can allow moisture to enter the light housing, resulting in condensation buildup.
- Water splashes or high-pressure washing: Driving through deep puddles or subjecting the vehicle to high-pressure water during car washes can force water into the turn signal lights, leading to moisture buildup.
- General wear caused by age: Over time, the internal components of the turn signal lights, such as the bulb sockets or wiring, may deteriorate, increasing the likelihood of moisture intrusion.
In many cars, the turn signal lights share space with the headlights or tail lights. This means that condensation can spread from these lights to the turn signal lights over time.
Does condensation mean that your turn signal lights need to be replaced?
If condensation is only appearing on your lights for short amounts of time or on cold mornings, then you shouldn’t worry. For a lot of cars, this is perfectly normal. Usually, the moisture will evaporate as you use the lights, or throughout the day as the temperature increases.
If condensation is consistently present on your turn signal lights, then it may be best to bring your car to a mechanic. Cracks in the seals, as well as other issues, can cause large amounts of moisture to accumulate around the lens. As well as affecting visibility, this can also cause the light to corrode or burn out. This can result in a more expensive replacement process. Our mechanics can assess the situation accurately, giving you quality advice on what needs to be fixed. The light may require resealing, or the cover may need to be replaced due to cracks or other damage.
Preventing moisture in your car’s lights:
To prevent moisture or condensation in turn signal lights, consider the following preventive measures:
- Regularly inspect the light assemblies for any signs of damage or worn-out seals.
- Ensure proper installation and alignment of the turn signal lights during replacements or repairs.
- Avoid exposing the lights to excessive water pressure during car washes.
- Address any cracks or damage to the light housing promptly, either by repairing or replacing the affected parts.
