General TR Warm White H4 LED Headlight Bulbs

Hi All

I wanted to share this in case it benefits anyone else. Super short story is I upgraded to H4 "Warm White" LED bulbs from ClassicCarLEDs in the UK and couldn't be more satisfied. They have a 3000*K color temperature and look 1000% period correct. I acknowledge the light distribution from an LED bulb is not the same as a true halogen but, for me, I almost never drive at night and the pros outweighed the cons. Cost for two bulb kit was about US$100.

Longer story, I own a 1966 Triumph TR4A for 22 years. I still run the 22 amp Lucas generator and halogen bulbs consume 10-12 amps. My initial search started because I wanted to run DRLs for safety with all the other cars on the road but, did not want to turn-on my 10amp halogens all the time.

After a long search last winter, these LED bulbs tick all the boxes:
  • 3000*K light color is perfect. No one can tell the difference from stock halogens (I was really concerned 3000*K would appear too yellow but, not at all). This was a huge consideration for me. My car is nearly stock and I did not want those 6000*K brilliant white bulbs near my car!
    • See photos below
  • LEDs arranged in an H4 format
  • These definitely give more light (reportedly 4500 lumens per pair vs 2500 to 3000 for halogens)
  • They consume ~1/3rd the power (reportedly 3 amps vs 10-12 amps for halogens)
  • They do not have an external fan like so many other LED bulbs (one less thing to break or fail)
  • They fit entirely into the stock headlight bucket with no modifications (the heatsink is reversible. there is a control box but, it all squeezed in there).
As an aside, I ended up installing a reproduction tri-pod headlight with a "city/side light" feature which accepts a 5 watt T10 bulb. I also got from ClassicCarLED's a warm white LED T10 which consumes 1.5 watts and wired that to the (+) side of my ignition coil - so now that functions as my DRL without having to turn on my parking lights on (they come on with the ignition key). Photos here (hopefully files are not too large)(on jack stands with front grill and bumper removed for other work):
