LED H4 bulb

[desertgasser300]

Thought I would try one of these. I don't ride at night unless I get stuck out somewhere after dark. I would only use it to find my way back to the truck. I am tired of replacing the filament bulb that rattles apart.

I will post up a pick in the dark when it comes in.

It might last longer but I don't think it will project any light as the sub heading says. I'll be interested to here how it turns out for you.

My bulb shatterd apart on my first ride. I didn't crash either. Got home and light wasn't working. Looked inside and just the filament was there. All the little bits were inside rattling around.....I'll be looking for the review.

I saw one of these on Amazon and I almost bought it for the lower power draw. Looking forward to reading how you like it.

As a "daytime running light" it only has to illuminate the lens. You will find the light pattern is bad. A couple of the LEDs will be close to the stock filament position so it should project a bit farther than the end of the front fender. As a get-back-to-the-truck light I'd give it a "maybe".

Yeah, it pretty much blows. Even as a daytime running light. It works at idle, but as soon as the revs go up the lamp goes out?

I have my street bike I can always put it in for a running light.

LED's don't work that well on AC current. Most likely the higher current is freaking it out.

I have my bike converted to DC so I never even thought to mention that. Good point and something I should have pointed out.

That is strange, is it fine hooked up to a 12V battery? Any chance your headlight is still on AC? Your battery should act like a big filter and provide stable DC if everything is set up right.

EDIT: LEDs will work on AC (correct voltage) but have slightly reduced output. Maybe that bulb has some special built-in electronics that require ideal conditions.

I have a kicker, no E-start.

A full wave rectifier powering the LED might work provided your voltage regulator is functioning. Before doing this I'd mount the bulb and power it with a car battery to see if it's adequate for your requirements. The light pattern would have to be good to justify the messing around.
