Aftermarket Incandescent Lights

Hey all, I'm having an issue trying to get 2 pairs of aftermarket lights running all at once. I had them on the front with stock lights on the back for a couple weeks, and now I finally took the jump today and installed the rear lights too. When I was running the bike with just one new pair, I noticed that my bike had the "hyper flash" issue, it didn't bother me, but now that I decided I wanted these things to match, I've opened the next can of worms. The store page claims that these are non-LED lights.

I made a video for you, I ramble a bit sorry about that. I do intend on replacing the wire butts with some smaller ones, I was just testing the lights out with them. I regret not splicing the "blades" on for both wire setups, an unfortunate mistake on my part there.


The lights I purchased - https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

Even if they’re not LED they may still run less juice than stock and you’ll either need a different relay to even out the pulse or you’ll need load resisters in line with the bulbs. That’s the basic fix with aftermarket lights. Why your lights are dimming I’m not 100% sure.

Hey thanks for the quick reply. Any chance you can point me in the direction of a relay that will work for me?

Honestly I haven’t looked into it personally. I changed my headlight and tail/brake lights to led but left the signals alone. But it’s as easy as “vn750 flasher relay” in google and before you know it you’ll have too many to choose from lol. Im hesitant that you stated that the new lights aren’t LED though. Somebody who’s lived it will chime in.

I think maybe the front bulbs are installed backward (depending on the type of bulb) or the wires are connected wrong. It looks like the brights are on all the time, and the lows are on the flasher side.

Don't know if that fixes the flasher or not. EP34 is the flasher for LED, and it works with all bulbs.

I don't know if they're backwards, they worked just fine before I installed these new rear ones. All of the lights are 2 wire, even though the front signals used to be 3 wire. I noticed they had hyper flash before I installed the new ones now I have no flash.

Ok that’s starting to make sense. The original were 3 wire because they share a common ground and one leg was for the running lights and the other leg was for the flashers. (One bulb, 2 filaments) The hyper-flash is due to the new bulbs not requiring as much juice as the stock bulbs and it throws off the electronics components a bit. But it’s starting to sound like you have two separate issues here

Ahhh, new info. I have no idea.

Do the new lights have double filaments?
