Where are the headlight relais?

Could be a dumb question, but where are those headlight relais? My right headlight is very dim, so I guess a failed relais is the cause as I read this here in many threads. Because I have at least 3 donor cars, I would have enough relais here, but I don't know how they look and where they are. Thanks!

I would check the voltage getting to the headlight middle lead and ground before going after a relay. If the voltage on the wire is 12 volts with the light on then you have a bad ground and not a bad relay. If the voltage is low then replace the relay.

Probably have to trace the wire back from the relay to ground, since subaru's use a switched ground system, right?
(my 88 GL has the same problem, a dim passenger side headlight)

Be sure to check the connector to the light also for burned contacts as this is a commom failure point.

I have the same problem and I am pretty sure it is the ground..Anyone able to tell me where to look for the ground wire for the driver side headlight? 87 GL. Thanks

Most of the time this kind of trouble is due to bad socket connections to the bulb. If one side of the lighting is ok then the connection ground for both sides is most likely ok though it is possible there could be a faulty connection between the two sides. To see if the connection to ground really is the trouble and not the bulb socket check the voltage to ground on the ground wire going to the dim light while the lights are on. If there is very little voltage on the ground wire then the ground is ok and the socket is the trouble. Also verify that full voltage is getting to the light.
