FW: 9007 bulbs in 9004 DOT headlites?
I tried to fit the 9007 bulbs in my 87 4k (fwd) this weekend to improve
the lighting of the car as suggested by Luis Marques. What I forgot to
do was to swap the wires. The result is that the 9007 bulbs are dimmer
then the 9004 and the high beam indicator light stays on all the time.
I will swap the wires tonight. Now, will I risk the chance of shorting
the bulb if I swap the wrong wires? Should I put a fuse in line before
I do it?
Also, I noticed that there is a some kind of bracket in the head light
housing and it actually casts a shadow on the lens. I can see the
benefit of bracket if it's painted silver or chrome plated to reflect
the light, but it's black. Is this the reason why US head lamps are
less desirable? I didn't see that type of brackets in my other car.
Has anyone try to cut it out to allow more light to project on to the
87 4000S 146K
