Posted: Fri Oct 13, 2017 12:16 pm Post subject: My "latest and greatest" LED brake and tail lights |
|
|
Simple and dirt cheap to boot!
The stock filament brake and tail lighting (especially the tail light) is rather anemic on K bikes.
On my K bikes I always modify the brake/tail lighting adding flashing LEDs and such.
On my latest K restore of a 93 LT I came up with what I think is my best yet.
What's needed:
4 "Eagle Eye" 9W Red LEDs from Fleabay - $0.99 each. These things are flippin' BRIGHT and will hurt your eyes if you look directly at them.
The other item is a GS-100A flasher module - a little over $2 on Fleabay.
There's a variety of ways to tap into the existing wiring but piggy back connectors work well and are easy to use on the K rear lighting.
The downside of the Eagle Eye LEDs is that the diameter of the threaded part is 10mm so you need to do a little drilling to install them.
In order to separate the tail lights from the brake lights to make braking more obvious, I installed the tail/running light ones where the rear fender extension mounting screws were and then installed the brake light LEDs in the upper license plate mounting bolts.
This video doesn't do the brightness of the Eagle Eyes justice but in real life they are quite bright.

Since these are just add-on LEDs tapped into the existing lighting no other modifications need to be made since the original filament brake and tail lights will keep the BMU happy.
I recently spent an evening riding over a dark mountain pass on a very rainy night with lots of water getting splashed in the air and was very confident that I could be seen from behind even in those very bad conditions.
4/21/18 - Electro-nerd update: These are sold as 9W which one might assume means 9 watts but that seems pretty dang high for an LED. I watched a YouTube review of them and the reviewer measured the current draw for one of them at 40 mA. At 12V nominal voltage that comes out to a power draw of 0.48 watts so despite how they are advertised they're really only using about 1/2 watt each which seems a lot more realistic for an LED.

I've put these on a couple of my bikes now and they're the best thing since sliced bread. _________________ 93 LT (x2)

I put 4 of these LEDs on the back of my K11LT, 2 for running (tail) lights that are on full time and 2 for brake lights that flash when you hit the brakes. As Duck said, it is painful to look directly at them! Should help protect my 6. Thanks for the tip. |

Hello Duck... Hello guys....
When I can see again, Im going to install the lights that arrived on Monday,,, but somewhere I saw a schematic online for this and cannot now find it. Anybody know where it can be found ???
Thanks in advance.....// Ernie in NH _________________ AMA,, American Deaf Bikers

No schematic. I can draw one if you'd like. _________________ 93 LT (x2)

Hi Duck....
I dont know the wire colors.... but a schematic might be helpful for others that are going to buy these LEDs.. We could keep it in the "stickies" for all future reference..
It'll be a while before I'm ready to dive in.....however I did manage to try the LEDs on the bench in garage ( a real comedy ) but wow they are bright ! The leads are super tiny but not fragile, what is that wire size, and how did you do the connections ??
Thanks,,,,,,,,,// Ernie in NH _________________ AMA,, American Deaf Bikers

G'Morning Duck...
Great pic from your SF "delivery run"... got to admit to being a bit jealous! I wont be doing any of that for a while although the prognosis ( for me) is "good to go" earlier than expected.
Now, it looks like the colors are " Gr/Blk ,, Gr/Y ,, and Br as ground " correct ?? From the diagram on the face of the strobe unit, it looks like both black leads are to be grounded ?? One of the "reds" is the 12v power "in", and the other red feeds the bank of LEDs..? Is any of that correct ???
Thanks in advance for your input....// Ernie in NH _________________ AMA,, American Deaf Bikers

I've added a wiring schematic to the initial post at the top of this thread. _________________ 93 LT (x2)

If you want to simplify this installation you could just use three of the Eagle Eye LEDs and mount them in the three holes that attach the rear fender extender. Put one tail light LED in the middle and then have two brake light LEDs in the outer holes.
That way you just need to drill three 10mm holes in plastic and you wouldn't have to mess with drilling the license plate and, if you have one, license plate
frame. _________________ 93 LT (x2)

This would be better if you want things to be simpler. |
