Headlights malfunctioning

[Heretic]

I have been having a problem with the headlights on the car shutting off momentarily and then turning back on again. This actually started a while back, but would only occur when the high beams were engaged. Lately, it has started doing this driving normally with the low beams. Also my interior lights do not work anymore, the dash lights are temporarily rigged with a switch and 5 amp fuse [They are all LED 194's]. I am thinking headlight switch but I would like a second opinion from you guys before I start replacing parts.

My car is an 85 police car, 351W. All running lights outside are LED, Silverstars are used for all 4 headlamps.

I'm going to agree on the headlight switch, and possibly a multifunction switch as well. Might want to consider a relay harness to take the load out of the headlamp switch. I did it with my car, got another 2.5 volts at the headlamps which made them significantly brighter, and removed most of the load on the switch which should make it last almost forever.

yep, and with a relayed harness you can make yer headlights do whatever you want to - I have my master switch control both the headlights and the fog lights, and if I hit the high beams it's near 700W of light shining down the road two counties away

My relay harness runs the lights just like stock, outers are low, inner+outer on high for high beams. I have 21 year old factory Sylvania halogen high beams and I dont even know what lows, and its a lot brighter than before, no yellow tint. I imagine with brand new better quality bulbs it would be better. I'm also curious what such a relay harness would do for my truck with the Silverstar bulbs it has.

I think you have wagner or ge halogen

Excellent, thanks for the second opinion[s]. Further research indicates that the actual switch apparently has some sort of circuit breaker system integrated into it. I will have to dig up a wiring diagram and do the headlight thing for this car. I remember there was a guy that made kits for the 94-96 F-series [9007 bulbs], but I am doubting someone makes a kit for out particular application. A few 40 amp relays and some good wiring will suffice.

I really like the Silverstars, they are nice and white, very bright, and aren't as expensive as switching to true HID would be. If someone on here has / can point me to some nice diagrams that would be well appreciated. I am, for the time being, going to change that switch though just to get me by before the wiring gets upgraded.

Silverstar Ultras are some badass lights, problem is at $25 they are fairly expensive and they don't last worth shit, I have to replace mine every like 9 months or so. I replaced my inboard ones with Xtra Visions, and I'm now waiting on the outboard ones to burn out to swap them out too - right one is already gone, I'd give the left one no more than a month before it goes too.

off topic....are you the guy with the lightning motor?

[Heretic]

My reputation proceeds me. Yes, I have two actually. One is a 94, one is a 95. Both F4TE roller ready.

[Heretic]

Any more information on a relay harness would be appreciated. I really do not feel like tracking down all the wiring myself. I know there are several on here who have done this, so anyinput would be appreciated! Thanks everyone!

Hi Heretic

Here you go dude fill your boots, Relayed Headlight Harnesses

Excellent... This may be the way I will go. That H4 conversion kit [4x6 bulbs] and the harness should work great, and these aren't horribly expensive. I will probably just trace down the wiring in the car and splice it in somewhere. Thank you for the linky...

[Heretic]

Still a problem

Well, I replaced the headlight switch [Pain in the ass!] and everything seems to behave much better now, except one thing. My interior lights in the gauges, speedo, and hvac control are not lighting stil. Is there a seperate fuse for these?

[gadget73]

Yes. I don't know which but there is a fuse dedicated for that circuit.

[FatNasty]

Fuse #13, its a 5 amp one
