Driving Light/ Light Bar Fogging Explained.
Press Release Valve
Condensaiton - Humid Air.
Rest assured, this can be visibly alarming, but the lens will always have a larger temperature differentation than the solid heat sink and as such any moisture that collects will be on the lens, far away from the PCB and LEDs.
Dry Out Solution.
To reduce moisture and clear it out of the light fixture we induce heat and air flow.
Heat will evaporate moisture into a gas and air flow will allow it to exit the light fixture.
Heat can be induced by either operating the light fixture for an extended period of time or more easily by parking your vehicle in the sun and allowing the black lights to heat up.
Air flow can be increased by removing the breather valve with a flat head screw driver. Once the moisture is cleared, replace the valve.
Step 1. Remove Breather Valve.
Step 2. Heat (Sun or operationg)
Is this normal?
We will often see this shortly after installation or even when unboxing as there may be a rapid temperature change to a light that has been stored in a box for some time. Typically, once cleared we rarely see an accumulation again and the breather valve allows for pressue equalisation, allowing hot air out and keeping water out.
Our lights are tested to 3200 PSI of hot water jetting and will hold up to the most extreme conditions. However, similar to how your vehicles windscreen may fog up from time to time, it's not that there is water ingress entering the light fixture as much as the moisture within the air is condensing on the lens.
You may have noticed this when washing a car and the headlights quickly fog up, often it's the cold water cooling the lens and in turn cooling the air within the headlight, air which contains moisture.
