Rd250 Honda headlight led

[Ballas03]

Hi guys, back on the old form I found out about putting a Honda headlight in that takes an h4 bulb the rd25/350 bucket. This was nice because it now takes a halogen bulb, but my problem is I still want better light and the low quality 35w h4 bulbs keep blowing out. I was looking to do an led but everyone I see has a huge heat sink. Was wondering if anyone has put an led bulb in the Honda h4 housing.

yes I have some experience running leds. no heat sink on this one.

I'm still running the original '75 RD350 headlight and am looking for upgrade options. I would like to go LED too, but this is the first I found about the Honda H4 Halogen. This would be an upgrade to the original headlight I'm sure. Any suggestions or alternate headlight setups you guys are using would be much appreciated.

I am currently using a 1980s Honda Shadow lens that lets me use an H4 bulb. It's almost a dead match, got this information last year on the old forum. I tried to use a larger watt bulb but it did not pan out so well and ended up just going to the 35/35w bulb but now I can change out my bulbs!

Will a stock system support that or would you need a vape system that would allow that much wattage?

stock. the description is a little retarded. 100w is the equivalent hid bulb, its probably actually 12w of current drain. 20,000 lumens is bullshit obviously. stock bulb is nearer 800 lumens.


here we have a case where mark puts one part and I put a different part with a different price. who is right? we both are. I'm also using another property he is not. the one I posted is 2,000 lumen. it uses just 5w. I need this because I often run batteryless.  but to answer your question all led's use just a fraction of the juice other bulbs use. modern stator repair is the led conversion. no vape needed.

To be fair - the 20000 lumen figure was for the pair of bulbs.

Not sure you get 10000 per bulb, but a big difference.

I just wish the temperature range was a bit lower...

the one I posted runs cold and is brighter than stock.

ive run those, the beam spread on those sucks, bad. on darker roads, etc, they are abysmal. i have the led bulbs like i posted on 6 of my bikes and no issues running them at 75-80 mph on dark roads at night.

in the city, i can see where it might not matter as much. .02

I think Brad-Man was talking about color temperature. 6000k is pretty stark white. H4 is probably around 4500k-5000k Stock even more "warm".
