Let there be light !!!...?

I am considering installing tri-bar halogen headlights in my 72 Mach1.
Years ago I upgraded to Halogens in my daily driver 69 Cougar. With the Halogens I experienced headlight "blink" they would cut out and a few seconds later back on & then out again. I up graded to a higher amperage alternator. Ultimately someone explained that the Halogens drawn more power ultimately over heating and triggering the relay to kick off. After cooling for a few seconds or maybe a minute the relay would cool off and the lights would work again. So I was wondering if this is an issue with 72 machs?
As always I appreciate any and all input,
Your friend .

P.S
If you saw my post about my car ending up in a cornfield, The insurance adjuster gave me a pretty good estimate. I should be able to get the damage fixed with a bit extra.

If you are going to upgrade head lights to higher wattage you should add relays to handle the higher current draw and save your headlight switch.

Hey Keith...It sounds like your keeping the Mach 1! Good to hear you may come out ahead a little.

Upping the wattage (in a replaceable globe unit) is never a good idea. The extra heat will reduce globe life and may damage (tarnish with heat damage) the reflector.
IMO using a new lamp unit with +X% extra LIGHT globes is a better option. Often these are lower wattage than the original globes due to the technology upgrades.
New relays will give better contact (less volt drop) than original switch gear.

Hi

I updated to H4 with relays, very cheap kit from autoparts store in sweden.

Her '70 Mach 1 has new 7" with +80% QH globes. No new switch gear as wattages lower.
The original switch gear (all curcuits) may benefit froma good bath in switch cleaner to remove oxidation and tarnish.
