Wash your headlights well using soapy water; rinse and dry. Dip a corner of your soft rag in denatured alcohol, which you can find at most paint or hardware stores. Rub the solution on your lens in small, circular motions. Repeat until your headlights lose some of their yellow hue.
Check the connector contacts for a short circuit, with a tester. Make sure that you are replacing the proper type of bulb. Inspect the lens for fogginess. It might seem odd, but overfilling the coolant water, will spill out of the top of the bottle as spray and vapor. This liquid somehow finds its way unto the passenger side bulb connector, and into the lens, causing temporary fogginess and possibly a short in the connector. It happened to me.
If both lenses are foggy chances are your bulbs are acting like fuses and when wet/damp blowing,reseal with silicon,or replace lenses.(when lenses get foggy it is also a sign that the chrome has oxidised.)
Foggy headlight lens is from water ingress and gets trapped in there, the easiest way for you is to unscrew the back of the headlight assembly and get a hair drier and just dry out the head light, it may come back after a few rains,, other wise undo the screw holding the headlight unit, disconect wires and remove unit, I have the submerged unit into water watching where air bubbles come from then apply a small bead of water proof flexible sealand or silastic around the edge where the cover and lense meet, Dont try to take the lense off you will break something. Dry out completly and use hair dryer agin on low setting to make sure all moisture is gone and reassemble back onto vehicle....
Most Auto Stores sell a headlight solution that cleans the fogginess of your headlight. Assuming your headlight looks dirty and cloudy as would a pool, a simple solution is to pick up the cleaner at any auto place. That is a lot cheaper than buying a new headlight.
At my shop we have a product from Ever-Wear, it is a headlight restoration kit, do it on the car and works great. Did one light on my car and left the other one foggy as a demo. Great Product
