Putting LEDs on Wife's New Used Bike

I put LED's on wife's bike. things went really well. I modified the license plate bracket so i could use it and the holder for all the Wires inside it. I think it looks pretty clean. just need to plug up all the left over holes. I also put in a new flasher relay. the relay works perfect with regular bulbs in the front blinkers I thought I needed to put LED's in all the blinkers but when i replaced the front bulbs the switch locked up. I am going to try another switch because I eventually want to put LED's on the front as well. if anyone has done it and has a part number for a working switch i would like to get it.

Sounds like you have the stock thermal flasher, which won't work with LEDs. Get an electronic flasher. It works with any type bulb.

it is a new switch/thermal flasher for LED's. I have read of over the link, thank you for that. It works with just rear LED's, but not front and rear LED's. my guess it is what I get for ordering from china for $2 (Wish or Joom) I will check for links here for other after market flasher switches for LED's unless someone would like to send me one.

What did you modify on the license bracket.
I have got to take it back apart and get pictures of it. I broke all the spot welds off and removed the braces, heated the metal and pounded the license plate part flat. this allowed me to use the spot containing the wiring "TURD" and keeping all the wires there. Like I said I will get pictures and post it hopefully tomorrow.

your turn signals work correctly with only the rear bulbs replaced with led
when you replace the front with led, it doesn't work correctly.


can you be more specific on what it does? 4 way flashers or always on or nothing comes on at all?


can you post a link to the flasher relay you used?


check that you have the battery and load connections correct, some flashers get flakey if they are wired backwards, most 'electronic for led' go steady-on-no-flash if the 2 wires are swapped.

It has taken me a while to take it all back apart and get pictures of the modified bracket. the first two picks are of the finished product. I heated and beat flat the two 90 degree bends in the bracket after removing the support pieces that where tack welded in. The first part i remove held the license plate light and reflectors that should be picture 3 and 4. if you look closel you can look where I broke the tack welds with a cold Steele chisel. I tried grinding them off with a Dremel but once i started using the chisel it was much more efficient.there where also two reinforcement pieces on the other side that you can see in pictures 3-5 I had beat these off with the cold chisel as well. I also modified the plastic cover however i have reached my picture limit for this post so it will have to wait for the next one.

I modified the plastic wire cover with a razor knife so that i could still use it with the license plate bracket. the first two pictures are of the cut piece and the third is what it looks like installed in the license plate bracket.I finally painted the Bracket taken everything apart and put it back together using heat shrink to protect all the wire connections and making everything look pretty.and when i got it all back together and on the bike it no longer worked it was like it had a short in the wiring when I turn on the blinkers now it is like I have fluttery hazards on. it worked perfect before the final assembly so here I go taking it apart again to see what is wrong.

I DID IT!!!

it is the little lite that tells you a blinker is on. it messes everything up. and i have figured it out my own way not any one else and I am ecstatic about it! instead of using electronic components to make the circuits going into the light one way I added a light. Yes I had to purchase another Harness but now my wife ,Elsie, A left blinker light and a right blinker light on her bike. That would be the first picture. I had to drill an extra hole where the Honda emblem used to be. I also changed the colors now the blinker lights are green and the neutral light is yellow. the second picture is of the plug with removed wires. this was the hardest part I spent over an hour removing the wires from the plug using a Hardened tool purchased off Wish.com. Warning I cut a knuckle on the plug every time I got a wire out. then I ran a single wire from the right and a single and a single wire from the left and the second wire from both the left and right to the ground coming from the headlight seen by the giant red splicer thing in picture three. I also had to remove the neutral wires from the plug and place them in again because the light itself changed from below to above on the dash. I am sure there are questions and more pictures to take and I watched a lot of videos online before I came to this solution, when I find the links i will post them again. i am just happy it worked.

I made a mistake I did not splice into the head light ground I spliced into the ground from the Speedometer light. everything was self contained in the dash assembly and just plugged back in when i was done.

If you use the new harness that comes you have to change over all the light bulbs. I used the new harness and the one lower light from the old harness. removing the light bulbs where a pain looking back i should have just used the old harness. you will also have to order one new light bulb for the neutral bulb when you are done those will now be your blinker bulbs.

I ordered the parts off of Partzilla. I had to go back and order that one neutral bulb if you order the bulb with everything else you will save on shipping. you may be able to find the parts for less some where else. those should be OEM part numbers and that should help.
