I'm working on some custom turn signals based off the Neopixel LEDs. They are RGB and can be individually controlled. They will go inside the stock housing. I am also ordering some clear lenses to put in front.

The goal is to have them act as running/brake lights (Red with blue center dot) and also as turn signals (yellow). I'm thinking about a progressive illumination pattern (in to out burst, or spiral fill, or horizontal wipe) for some more fun.

I have it next to a stock turn signal running at 14.4 volts for comparison. It's not quite as bright as the stock signal. That may derail the whole project, if I can't get the brightness up.

Neat! But complicated
Are you going to have to drive them with an Arduino board or what?!
I have something similar in a stage prop lightsaber I got at a Comic-Con with my son. Have to plug it into a laptop to change the color and sound parameters...

I'm going to use an Arduino Nano in a waterproof case to drive them. I'll run the factory turn signal and brake wires into the inputs (after conditioning them down to 5 volts), to trigger the different signals. Of course, I'll need to change the flasher to an LED compatible one, and move & upgrade the rectifier to deal with the different electrical load.

I was going to put some around the side reflector (as a frame) to provide a side marker. I want to run a strip along the underside of the frame as a road glow, and over the engine as well. I want it to look classy, rather than over-the-top.

I'm starting with the rear signals. If it goes well, then I'll move on to the front signals, the side marker lights, the frame lights, the license plate light, and finally the brake light. The headlight is a different animal. I have to change more circuitry, and there's no advantage for me to design my own LED headlight, over buying an off-the-shelf model.

Parts list so far
Per Signal:
8 count LED black PCB
16 count LED ring
Super Bright RGB LED x2 for rear
Super Bright White LED x1-2 for front
Custom driving board for Super Bright LEDs
Clear Lenses (2 pack, 1 lens per signal)

The frame, side markers etc use these strips
144/m strips (free leftovers :) )

Per System:
Arduino Nano (3 pack, only 1 needed)
5V power (2 - 3 needed)

Plus a few odds and ends to connect it all.

Please don't add up all the costs and tell me that it'd be cheaper to just by X lights by Y brand. I don't want to know. ;) Building my own is part of the fun.

Status Update, my coworker designed a bracket to mount a high power LED inside the turn signal housing, and utilize the built in reflector! We have a 3D printer at work, so I tested one out.

It is a little tight on the mounting tabs, and I had to cut 4 of them off. It also interferes with the lens slightly so it needs an adjustment. However, it placed the LED in exactly the right spot to perfectly use the mirror!

What's nice about this bracket is the LED size is an industry standard size for 1-10 Watt LEDs. It holds two LEDs, with one facing the mirror, and one facing outward. You could use White LEDs with the factory lenses if you desired.

I took some pictures with a single 2 Watt RGB LED behind the smoked clear lens. It is about as bright as the 21 Watt bulb behind the Amber lens. I only had one LED, so there wasn't one facing the lens, causing a dark spot. The two images were taken with the same camera at the same exposure settings.

When I add the forward facing LED, I am considering running it blue, for a nice blue dot brake/running light (legal in IL!). Since the color is controlled by code, I can add a switch to go to solid red if I travel out of state.

When I use the turn signal, I'll turn the LEDs to 100% Red plus about 75% Green, for a simulated amber signal.

In the front signals, I am planning on using a pair of RGBW LEDs. While running, I'll use 100% white plus some Red and Green (to warm up the color tone and try to match the headlight color). When turning, I'll switch to 100% Red plus 75% Green to simulate amber.

I'm pretty excited about trying to blend LEDs into an older bike. I may even put in the code, a gradual turn on/off to simulate incandescent bulbs, when turning, or coming off the brakes.
However when applying the brakes, I'll probably do a quick 2-3x flash followed by steady on, just to get peoples' attention.

This is cool! Keep sharing the progress, I love seeing electronics projects like these, and can't wait to see how they look on the bike in action

Winter turned to spring, and spring turned to riding, so this project stopped!
Well I'm back in the off-season and taking another crack at it.

This time, I'm using some high powered LEDs from Cree.
The XML series, capable of 1A per color.

I mounted two in the original housing, using the screw posts to mount the bracket.
One faces outward, and the second faces the backside and uses the factory mirror.

The left images are the stock bulb with the amber lens, from straight on and from the side.
The right images are the LEDs with a smoked clear lens, from straight on and from the side.
I also took pictures of the LED with the white turned on. Not as bright as the red.

The brightness is comparable. The previous approach was not.

Next is the controller that I need to build for this.
Since the LEDs are RGBW, the rear will function as running lights (RED), brake lights (RED) and turn signals (RED + GREEN). The front will function as running lights (WHITE) and turn signals (RED + GREEN = amber).
