After many a search, I have conlcluded that there are no quality aftermarket options for led or xenon bulbs that function well in the factory headlights for that body style. My 02 suburban has tried many different bulbs. The headlight housing just doesn’t support the light source with the reflector. All the aftermarket headlights to add a projector lens look like Chinese crap...and nothing new is coming out for the older trucks that looks any better. I have resorted to the highest quality halogen bulbs I can find and upgraded the wiring for the wattage.
Dont get me wrong, the zen is and latest led bulbs are super bright, they’re just not controllable in the headlight. The light goes everywhere!!

I use the PIAA extreme white plus and I found that the oem reflectors are far better than the aftermarket replacements. I found a pair of factory headlights that were still in good shape and had them clear coated to preserve them. The aftermarket ones that look like oem don’t last long and the reflectors are crap. I may try the latest PIAA LEDs when one of these burn out, but I’m definitely sworn off of the Chinese LEDs. PIAA claims the beam is engineered for a reflector housing...but it will cost me a couple hundred bucks to find out...again.
