High-wattage headlamps?

I agree for its simplicity a relay setup is a MUST, a new switch isnt good enough.. Its rewards are twofold. By removing the headlight load from the switch you not only have brighter headlights but the extra amperage thru the switch will brighten those horribly dim tail lights to a modern level too. Ive got my H4 headlights on a 3 relay setup that allows the high and low beam elements to light together in when the high beams are selected.. Its pretty impressive for a 40 yr old car.

My instrument panel lights also seem to be brighter......

That too, in the original confiuration everything is fed off that headlight switch. By using the relays all of the power previously consumed by the headlights is now available for the small stuff that it should have only fed in the first place. With 40 yr old wiring, switching to relays for high draw items also reduces the chance of fire.

It's all good. Win-win. Reasonably priced plus easy to do!!!!

Thanks everyone, thats good to hear. Where can I get such a kit and is it universal(or Ford/Mustang specific)?


Painless Wiring sells an H4 Halogen headlamp harness, too. It plugs into one of the headlamp sockets on the factory harness. It's not Mustang-specific, but it may as well be - works great.

So you have the Painless kit and H4s?

I thought of another question; For those that have H4 conversions, how is the beam pattern? Does it have good spread or is it artifacted at all?

Once you use H4 lamps you will never go back.

ARTIFACTED?????

Its a term commonly used to describe a defect in digital images or video where the picture is broken up. An example is when a jpeg image is compressed so badly that it looks like crap. When Applied to headlights, it means the light is not smooth and even, but brighter or darker in areas. The reason I asked is because the cheap repro '87-93 'Stang headlights tend to have a crappy beam pattern.
