Just got n oil change and my mechanic advised to use LED bulbs. But they're really dim. I'll go back tomorrow for another adjust
ment, is it possible that LEDs don't wok in a 20-yer old (1999) car?

 

Very possible, tell you mechanic to refund your money and put in OEM spec bulbs.

 

I've now read a few UV-C projects where they tested various bulbs and there were wild inconsistencies in output not just between manufacturers but between bulbs of the same make/model.

He put in the wrong LED lights. I tried a couple before I found a really excellent set, the Sealight X4 series. Brighter than HID, maintains a sharp cutoff pattern on low beam and the high beam lights up a mile down the road like a carbon arc search lamp. These lights are literally like night and day on my daughter's CX-9.

 

I too have found LED lights are very varied. I actually got flagged by the VIrginia vehicle inspection guy for having LED lights that were not legal because they were too low in light level. I went back to halogen. LEDs from the factory are the best way to get LEDs that match your vehicle and legally supported.
