2001 Ram 1500, Quadcab
Have extremely dim headlights, both low and hi beam on an old truck. Hi beams are brighter than low beams, but still very dim.
Started investigating and am thoroughly confused.
Attached is a picture, with post call outs (A, B, C) for reference.
With no bulbs installed here are the voltage measurements I get:
(Passenger Side listed 1st)
Off: A = 11.68V / 11.48V, B = 0V / 0V, C = 12.07V / 11.96V
Lo Beams: A = 11.28V / 11.27V, B = .01V / .01V, C = 11.72V / 11.71V
Hi Beams: A = .07V / .03V, B = 0V / 0V, C = 11.69V / 11.64V
When I started trying to figure out dim lighting issue, 9004s were installed. Based on the voltage readings in the attachment, and my internet research, it appeared to me that 9007s should be installed.
When the 9004s are installed the Passenger Hi Beam does not work, low beam does. Both hi and low work on Driver's side. Hi-beam indicator on instrument panel works as it is supposed to.
With 9007s installed both low and hi beams work on both sides, however, the hi-beam indicator on the instrument panel will not extinguish in either setting.
With either bulb, the lights are extremely dim. Not sure if I am dealing with multiple problems. All fuses appear to be good. I swapped light relay with a suitable and no change.
Does anything look obvious? And which bulbs should be installed? Any help would be really appreciated.
