DIY LED tail lights

[eyduc]

That's a possibility.  I'd have to lay out a PCB and get an estimate.   If I were to sell it, it would have to be real circuit board.   Also, I would experiment more with brightness.   My settings were fine to my eye.   Maybe an option to offer flashing brakes.  If flashing, the LEDs can be brighter due to the duty cycling.    For example, if the duty cycle was 50% (half on, half off), then the current can theoretically be doubled.    I believe the EP35 is a fixed duty cycle but there are two.  One for operating bulbs (lower resistance, slower rate) and one for broken bulbs (higher resistance, faster rate).   I set mine up for the faster rate.   The higher resistance will emit less heat.

Idea; have the turning signals light up as an arrow pointing left right..  only prpblem maybe is if your hitting breaks at the same time.. then again you could use amber leds for torning..

It's hard to take the brake lights but I'll try again later tonight.  I also have a vid but I'll upload and post it tonight.   When the brake lights turn on, the camera exposes it darker (like shooting in snow) and all you see are bright leds in a dark room.  It doesn't help that the background wall is (Ducati) red!!

What if you turn on the light in the room and or take the pic from farther away?

I was thinking about that idea too with the turns.  But I think it would be too much flashing going on.  I'll keep it seperate for now.   The turns are amber LEDs.  The cool feature on these is that you can see the flashing even on the front part of the turns.  There is an LED on the tip that can be seen from the front. 

As far as the pic, it was with the light on.  But the camera will adjust.   It was a little close too.   The reason is that the bike is up against the wall and so is the rear.  I'll have to move it around.   Will do it later tonight.

Ok, here is a link to a video:

Here are some shots.  Keep in mind all of the following are shot at 2 stops underexposed, but it gives you a relative idea of the brightness.

left turn & right turn:



The tail light is at similar or lower brightness as the turns.

Don't pay any attention to my house outfit..

Eyeduc,

Did I read that you needed resistors for the LED turn signals?

Also

What Mirror do you have?

Nicely done!

[eyduc]

Thanks, Hank.  No, the resistors for the turns are built-in.  The mirror is just an ebay CRG bar-end 3" knock off, mounted 90 degrees.  It's not bad quality for the price.  I wanted the mirror on the stock location but just shorter.   I don't really like the mirror on the end of the bars.

Im probally going to steal that idea, but then again what is this board for?
