Brighter turn Signals and indicator

I'm pretty anal about increasing my visibility on the road as much as I can. My greatest fear when riding is to have some SUV-herding soccer mom, engrossed with her cell phone, T-bone me while stopped at a traffic light. There wouldn't be a lot of defense for that.

That said, when I recently added OEM-style turn signal lights to my Commando, I was underwhelmed at the visibility of these lights. First, the new Lucas flasher works sporadically, with flash frequencies varying wildly. Then the archaic wiring diagram of the headlight-mounted indicator light makes it a joke during daylight hours. You'd have to cup your hand over the indicator to see if it was on or not.

In an attempt to improve this situation, I stumbled onto to a British LED specialist: http://www.dynamoregulatorconversions.com/ , and it looked like they provide just what I needed.

For well under $100, I purchased a new 2-pin LED Brake light bulb, 4 turn signal bulbs, a solid-state flasher module (required for LED lights), and a specially-wired indicator LED (Part No. 9), which fits perfectly in the original headlight bucket opening, and looks like the original.

Wiring was simple. Just replace the bulbs, remove your seat and change out the flasher unit, then remove the headlight, unplug and remove the old flasher indicator, and replace with the new one. (You WILL need to order a package of Lucas-style brass connector bullets, and you may as well get a package of bullet sleeves (double style)).

When all was finished, all the lights on my bike now work the way a modern bike should. The brake light is much brighter than standard, and if course uses much less current, the turn signals as well are very bright, and flash at a consistent and proper rate, and the flasher indicator is sufficiently bright during the day.

They also sell a turn signal warning buzzer that I may consider.. a feature I've always liked on my old BMW airhead.

Highly recommended!

Could you please take some pictures of the finished product? I'm always looking at ways to improve my lights. Jean did a very nice writeup on his home-made LED replacements. I was originally going the route of replacing the existing bulbs with LED drop-ins since it's the easiest route, but Jean's solution allows for cramming more LEDs into the housings. Check out his turn signal:

It's best you not know what that signal goes to...

Wouldn't happen to have specific part numbers would you? Thanks.
Here are the items I purchased:
Part No. 4: 12V Amber BA15 lamps for turn signals
Part No. 6: LED compatible Flasher Unit
Part No. 8: LED Flasher Fix Kit with Tell-Tale indicator light (fits in original headlight bucket, same color and size as OEM, slightly different pattern in the jeweled lens) (be sure and order the solder bullets, as the unit comes with just bare pigtails)
Part BAY15d stop/tail light (there are more powerful options, including those with white/red segments, but I am happy with this bulb, about the same physical size as original 1157 2 pin)

I also replaced my original charge lamp and eliminated the gadawful "warning Light Assimilator" from the circuitry, with a less-than-$30 solid state circuit and warning LED, which fits perfectly in the original "charge" light lens bezel. The little circuit box is smaller than a match box, and fits easily inside the headlight nacelle. This came from http://www.improvingclassicmotorcycles.com. This is more than just an on-off light. It comes on with the key, then turns on and off when running to show the true state of system charging/discharging (the light is almost always on at idle if headlight is on). As well, it goes into a special flashing mode for under-voltage (a warning against the dreaded Boyer ignition low-voltage kickback) and over-charging.

I'm not necessarily promoting these companies but have been very pleased with the quality, price, and responsiveness of both.

Finally, by request, I took a short video of the lights in action. The green light on the headlamp bezel is the much brighter flasher indicator, while the red light is the new solid-state voltage indicator. Notice how it comes on and off as the flasher circuitry draws power:

Phil,
What headlight bulb do you run with this set-up?

I haven't changed the headlight bulb. I don't ride at night, yet the OEM bulb seems quite appropriate if I did. I guess the only reason to switch to LED (expensive) would be to reduce the drain on the charging system, as I DO like to run my headlights daytime for safety.
