Odd electrical..old work, new dont

[memper]

Decided to hook up the new front led signals to match the new rear led's. PO had the front signals in a box, still wrapped in bubble wrap.
At this time all lights worked and I disconnected the stock front bulbs at the bullet connectors, then hooked up the new led's in their place. No blinkers at all. No action at the front and about two of the little bulbs in each rear were at a dull constant glow. Cannot hear rhe tick of the flasher relay.
So I disconnect the fronts and put the stock bulbs back on and all four flasher work fine, relay ticks normally. (Ps- no resistors are installed yet)
What's going on here?

What bike?

If it's an older model you can try a heavy duty (Ind# 552) flasher.

install resistors

Its a 99 750 dark. So just resistors will solve this? I thought the signals should at least work but flash too fast, which resistors would solve by reducing the current to the less power hungry led's.
So is it a new relay or a set of resistors that i need? I suppose trial and error will  clear it up. I will attempt the resistors first.

Resistors add load to the circuitry to cause the factory thermal flasher to cycle.

Best option (IMO) is to swap out the thermal flasher unit for an electronic one.  The electronic ones don't use the circuit load to cycle, they just do it no matter the load.  It's a simpler install and I've seen resistors melt plastic used to mount them...

Ok cool. I was just reading up on general resistor info and they can be prone to melting which means getting back into the wires again to replace. I'll just go the suggested route of a new flasher. So any Autozone 552 dual prong would be fine?

According to Stu I'm wrong.

You don't have enough load to cycle a 552.

Get the electronic one.

Got it. Thanks a bunch

Take your existing flasher to AutoZone and buy the electronic replacement unit that matches the stock unit.  (it may be a little taller)  Plug it in and go.
