Headlight Question

[85vette]

I had a driver side headlight that I thought was burned out, so after I spotted Scorp508's great instructions I decided to replace the sealed beams with some H4 type halogen units.
I picked up some Bosch lights today and put them in but the driver side is so dim it is useless--the other one is fine.
Any ideas on causes? I guess there are some relays and things involved in this wiring setup which may need to be checked?

-for future reference--the low beam and high beam were both dim which meant it was a ground problem
-I checked all the grounds I could find and they were gooe
-it turned out to be a ground wire by the headlight
all is good now

It's a fact as wiring and grounds age there resistance increases. To find out how much check the headlight voltage vs battery voltage. Mine was over 1/2 volt lower. Low voltage has a marked effect on light output.
I installed relays and Ciebe lamps with 100/130watt bulbs. Now I see things at night in time to drive around them. The superior design of the lamps don't blind oncomming drivers and there is very little back dazzel off rain now. It was worth the money.
