Default Re: LED Headlight with fog light issue...

Was out to Pizza Night on Friday and decided to use LED headlamps which I normally don’t bother w. I usually use HID fogs. It looks like headlamps need an alignment adjustment. Anyone have a procedure and/or headlight aiming tool for this? Seems mine are not reaching out quite far enough even for low beams.

What worked best 4 me was 1st to sit in the car w/ half tank of glass on level road and adjust the low beam cutoff to intersect the road at approximately 300 feet. Then check the high beam pattern height and check the pattern to see if it shines just a little above eye level seen from the drivers seat.

The high beam pattern location depends on which lights are installed, is why one optimizes the LO beam cutoff first to assure safety (NOT going to blind on-coming traffic).

Then, once happy with beam height, look to see that the LO beam pattern illuminates the road AND the shoulder (especially the RIGHT shoulder!)

*NOTE: I found that all LED headlights are not created equal, resulting in less than ideal results with some headlight aiming jigs. And, regardless of what jig is used, ACTUAL TESTING is the only way to be sure it's "right". Being that our cars are so low to the ground, we have a little more latitude for adjustment than other vehicles (long as the cutoff is @ or below our eye level), e.g., why trucks have their lights mounted low, relative to the driver's view! That said, if several ppl flash their HI beams @ you, you might need to depress the lights about one revolution (on adjustment screws). Also, shining the lights on a garage door is a good way to adjust the cutoff heights.
