Hello, I have tried installing led lights to my 95 cbr600f and the rear ones work but the front ones don't..... I checked the leds work and they do but when connected to bike..... Nothing, the bulb lights still work when connected but not the new leds.... I changed the flasher relay to led one after the leds just stayed on without flashing...... So currently have bulb lights on front and leds on back and they all work in this configuration .... Any ideas people?

 

LED's are polarity sensitive. Check you wiring to confirm ground is ground and hot is hot.
If the rears are working, I would suspect a polarity problem up front.

 

Did a swap of wires and they now flashing properly, thank you so much..... Only issue I have now is that only 6 of the 12 leds in each light are flashing, don't suppose you know why..... The lights have built in resistors and I have an led relay. Reason for both is I thought the led lights with resistors would work as the seller said they would..... And they didn't so got the relay and now at the point described above?

 

I just had a thought if only half the leds are working due to resistor and relay, would some led lights without resistors work fine, please?

Once again thank you ever so much for your help with this I am very grateful and will ride around with half lighting ones till issue sorted.... At least all 4 are the same now
