Buuuuut, anything is wortth a try I suppose. Ill see how others fair.
The OEM "weep holes" IMO are too low to fully vent the moisture that enters the headlight housing. When water turns to vapor it rises. It does not go sideways..... Stupid engineers.....
I've done the "drill a hole" method in many headlight lenses over the years and it's always worked out just fine. Never noticed any difference in the life span of the lamps.
I used a much smaller drill bit though (1/64"), and put 2 holes in the bottom of the lens (one on each side), and 1 hole in the top at the highest point on the lens. When the headlights are on, the heat will turn the water into vapor. As the vapor rises and exits thru the top hole, cooler dry air will be drawn in thru the bottom holes (natural convection). I used a 1/64" drill bit because rain water will not enter a hole that small on it's own, but it's large enough for the air and water vapor to exit.
