headlight issue (1 Viewer)

[Jay Lunde]

Hello. I am new to this forum. I have a 1978 chinook mini-motor home. But basically the issue falls into pickup category. A year ago, the dims quit working, so I have to drive with brights on all the time. This style has 4 headlights, and only 2 light up for dims position. I have been told by someone that it is the headlight relay. I bought a substitution at a parts store, but it does not work at all, for brights or dims. It is a multi-purpose relay they said and all they could get. A local toyota dealer says they cannot get that part; vehicle is too old and they don't want to talk to me.
Any advice or direction? Am I wrong in thinking it is in the relay? Is there a great online source for detailed guidance that anyone knows of? I have a Chilton's book for pickups 1970-81 and it is pretty good, but no detailed discussion about just this problem.

Not familiar with your rig. I'd guess the issue is in the Hi beam/Low beam switch. Is the cab based on a Hilux or mini truck? If you don't get the issue figured out. Post up a picture of your stalk in the 95-older Toyota truck forum. I doubt this General Tech forum gets much traffic.

Headlight woes

Here's the problem low beams work perfect, high beams only work on flash mode. I have taken apart the column and cleaned out the combo switch. I switch on brights, the light on the dash lights up, but the headlights die. I've been trying hard to fix this problem but cannot figure this one out.

Low beam head lights not working

The low beam heads lights decided not to work any more. They work in high beam but not low, which is confusing cause that means there is current going to the bulbs and the bulbs are functional. I googled this problem to see if any one has ran into this before and there is not much out there...

Brighter Head Lights

Hey thanks. Problem was just burned out filaments in the 2 outer bulbs (the rig has 4). I am not really bright when it comes to electrical stuff, and the outer ones came on along with the 2 inner bulbs for brights position, so... I thought well it is not the bulbs because they come on so are not burned out. But apparently the low-beam filaments on those outer bulbs was burned out but not other filament. So... working perfectly now. Thanks again, and I will hopefully be able to keep your guidance to go into that other forum. BTW, I don't understand about "hilux". I think mine is just the standard long-bed pickup style with the camper body set on it. It is only 18' long. I've seen lots of reference to hilux... curious. Someday I will have oodles of time to peruse and get familiar with ALL models. Sure happy to have mine roadworthy now; legit and all.
