Of course everyone knows that in their owners manual there is a listing too? Google 20/19XX RAM owners manual and in most cases it will be out there electronically.

Are the quad low beam bulbs the same as the Projector headlights on the 4th gens? if so i might upgrade the headlights to projectors. They make the truck look so much nicer

Just as a reference for headlights, check this page out. They have done a metric **** ton of bulb testing with various brand and model bulbs in various housings. They even have a list of videos specific to the 4th gen rams.

I ended replacing my light assemblies for aftermarket projectors (knock off's of the MORIMOTTO). My original lights were single bulbs (dual function: low & high beams) on right and left sides. The new assemblies are quad projectors. The light output and beam pattern on the low beam saw major improvement. The assemblies came regular H-1 halogen bulbs for both the high and low beams, but I did replace them with brighter bulbs from Autozone.

I wish I could figure a way to have all four projectors light up when on high beams. As it is now, only the high beam projectors or the low beam projectors will stay lit in their respective modes. If both were able to stay lit, the improvement to the light pattern would near perfect. The low beams really light up the area in front of the truck, but when switching to high beams, the distance is great but the area just in front of the truck loses the low beams and it is not so bright. My truck is a 2011 ST. I understand later models don't have this problem.

The trucks that came with single filament dual bulb stock housings were programmed to have lows on with highs. I bought an obdlink mx and the alfaobd app and was able to flash the truck with new the info for the new housings and have it work. I originally had the single bulb dual filament housings.
