Sequential blinker not working

[u/Ecstatic_Leopard_109]

Alright smart people, anyone experienced this issue or have any ideas for a not so electrical savvy person? So far my internet searches have let me down..

I have a 2026 xsr700 and just did the tst tail tidy mod which resulted in needing to upgrade my stock rear blinkers. I picked up some tst LED sequential blinkers but only 2 of the 6 bulbs flash and they are really dim. Like its not getting enough power long enough to fully light up.

I put them straight to the battery and the blinkers work so the parts are good. Signal fuze is good. I started with butt connectors and figured it was a bad connection so I soldered them on with the same poor result. I dont have an external signal relay to mess with or swap since its all incorporated on this year from what ive read and I dont see any other spot to wire them in to skip whatever is controlling the rate of power.

Ive read on relays, resistors and diodes and none describe my issue or give hints on how to solve it. It all mentions flashing too fast or being stuck on which is the opposite of my problem.

Anyone fixed this before?
