I wrote the other day that I had a problem with my tail lights on my 49
panel. I put an additional rear light on the rear door (right side light) in
order to have better brake lights and turn signals. I was having a problem
with the new light (right side) not working properly, i.e. the light goes
out completely when the lights are on and the brake is applied. The left
light works ok when this happens. Also when the brake light is on, the new
one is dimmer than the left side or original light.
A couple of responses indicated I had a groung problem. I removed the buld
socket bracket and put in a new set of contacts, ground all the paint off of
the area on the bulb holder bracket where it touches the light housing and
the similar area on the tail light housing. Put it back together and same
thing happens. Also ran a seperate ground wire from the tail light
attaching bolt to the body, by passing the door hinge as a grounding source,
but no change. The wires go from the light switch and the brake switch back
to the left side door body contacts and then a wire for each of the right
side lights is pigtailed off of that switch.
A couple more observations on the problem. Whether the brake is on or the
tail light is on in the new light, the same filament is lit, the dimmer or
smaller filament. This is the case even if I switch the wires. I am
getting voltage (using a test light) through both contacts in the new tail
light bulb socket with the brake light and the tail light on. When the bulb
is in, it just goes blank when both lights are turned on. Also, I noticed
that when the left side door contacts are not touching (the left side door
is open) the right side light will not work at all when the door is held
closed so the right side contacts are closed.
Thank you for any additional insights you may have on this problem.
