I searched and did not find a lot on this . I installed a new head light switch last year and then I thought then I needed to perhaps install relays to reduce the load on the switch. Many years ago I did the mod that caused the high and low beams to come on when the high is activated . That may have not been a great idea long term . I don't remember exactly how I did the mod as that was a long time ago . I searched the net but I did not find the information . . At any rate I was thinking that a set of relays installed to carry the load in the head light circuit would reduce the load to just what the current is of the coils in the relays . I got a couple of 4 pin relays and the harness to install but I was wondering if any one has done this . I did a little today to try to see what would be best way to wire this in . If any one has done this I appreciate your advice thanks Jim

Sir I appreciate the response

 

Well I found a few documents on the net about this and I finally called LMC trucks and asked a person there about a harness to fit my truck but they could not find any thing . So I went out on the net and found more information about different ways to fix or suggestion on how to reduce load on the head light switch . Finally I ran onto the correct part from LMC on the net . So I called back to LMC and gave them the part number and asked they to double check to be sure it the harness would fit . A 95 4x4 with out sport head lights . Ordered the heavy duty head light harness . I could have built a harness or cut up and harness and added my 2 4 pin relays . I going to just install the harness and try that first . I not sure of the quality of the harness from LMC but if its ok and works as designed the price Is cheaper than a burned up harness or truck

 

I ordered the kit from LMC trucks and installed the harness . The harness seemed to be a bit short so I changed that so it worked as I wanted it . The lights seem to work good . The main purpose was to reduce the load on the switch and harness .

 

If you still have high and low on together and now supply enough power through the relays you risk melting up your headlights.
(And a much reduced bulb life, but they are cheap)

 

That's true and I had given that some thought . Early on when I had heard of the mod and it was a long time ago I read how to make the change on the forum. So I did the modification and it seemed to make the lights a bit brighter . I don't use the truck a lot and finally morning on the way to work I smelled a burning like a insulating material while the fan was on . So I assumed the fan motor lol . Wrong . I remembered about the harness and head light switches problems on Dodges I pulled it down and yea . I realized now that the mod probably just made the problem a lot worse . The fact that I only use the truck for just towing or when my cars is not available probably saved my butt . I replaced the switch and repaired the harness and used anti ox on the harness connection . So I since fixed the load on at least the head lights to a min on the switch , there is still the tail lights but I not sure that's a big problem . . . The lights are very good even on low . If the bulbs burning out becomes a problem I try to get rid of the modification to the lights to make high and low come on together . Its been a long time ago and I don't remember exactly how I did it lol ****

 

I think the most "fashionable" way to do the mod was to connect 2 wires in the steering wheel column wiring loom.

If you run with both filaments on for a long time it gets a bit dicey for the headlight housings, you may be lucky or not.

Did you also add a good ground for the headlights?
One ground that seems to like to corrode is the one behind the drivers side headlight, leads to a lot of freaky problems.

Regarding tail lights- the switch had to carry the power for 2x55W(headlights) ,2x 5W front corners, 2x5W (Taillights) and on the 3500 the side markers and roof lights.
So going from at least 130W to 20W should add some longevity to the switch.

 

Yes Sir I the head light harness has a ground that attached to I think the left hand side and I ran that directly to a battery ground on both side . I appreciate the information on the mod as it was a long time ago . If I start to have problems I try to reverse it . This truck is only used to tow my trailers and I don't do a lot of night time driving so I see how it goes . When I got this truck in 98 it had 45 of so k and now its got 214k . I finally retired and now I going to do a few things to the truck that I always disliked . The front axle and the transmission . Thanks for your advice
