I have PNP HID's in my highs and lows with the XB LED fog lights already and I think the light output is fantastic to the point where my lightbars don't hardly do anything distance wise but they do spread more light to the ditches. I was entertaining the thought of trying the Morimoto FX-Rs. Just wanted to look at pricing and whatnot for now.
If you don't notice much difference between your light bar and headlights, then you already have your first problem. I've tried a lot. Not much I haven't tried.
2006 gmc sierra:
Stock headlights: bad
Stock headlights with silverstar/piaa: looked brighter, but went through bulbs like crazy, cost a small fortune
Stock headlights with 5000k lows 35w ballast and 6000k highs 55w ballasts fog lights 3000k 35w ballasts: no real difference between highs and lows, delay was atrocious, fog lights were less then useless in bad weather...I gave up using them completely
Stock denali projector headlights: halogens were slightly better then stock sierra lights
Stock denali projectors with 6000k low beam on 55w ballast: aimed lights so far down that there were basically useless, went back to halogen highbeam, HIR bulb, first huge increase in output...could see!
Retrofitted denali headlights: morimoto mini upgrade, 4300k 35w ballast and HIR highbeam...epic output and have never been flashed or bothered by cops for illegal headlights. Ran high beam splitter, had issues with 1 shutter on a projector so just unhooked them, always meant to get in tough with the dealer to get a replacement projector but never had time.
Added 30" rigid e2 lightbar: holy
, blows highbeams out of the water, you feel like you have no headlights on when you shut this off.
In a nut shell, retrofit is the best solution. Run the 4500k bulb on a 35w ballast if you want the best output. Imo 4500k matches the gmc led headlights perfectly. Will be doing an fxr upgrade on my wife's 2014 when warrantee is up. If your lightbar is not significantly brighter then your highbeams and you are basically using them as a flood light, then you wasted money on a lightbar that wasn't worth the money. As for the LED vs HID debate, the only thing led has going for it is instant on/off...that's it. There's a reason most cars with oem led headlights have more then 1 led headlamp per side...not enough output. Last time I checked you were looking at around 2000 lumens verse 34-3600lumens.
Hope that gives some insight to some of you guys who are maybe on the fence.
