Traf-X LED indicator advice please

[CVSensei]

Could anyone please let me know whether I need resistors to fit new indicators? This site is offering a discounted version for the units without resistors.


This is them:

Also might I need these? Definitely don't want to go cutting wires.

Bare in mind I'm a complete novice, I'm not even sure what a resistor is! Cheers for any advice

I needed resistors with my Rizoma indicators (without they flash quickly). And yes to avoid cutting wires the adapters are handy

Thanks bud, will buy them all just in case.

I'm intending to just replace the relay with one that's for LEDs... much neater and no faffing about with resistors.
