Hi just fitted some aftermarket indicators, when only front are connected they flash at correct speed but when rear are conected they flash fast.
I have fast flashing before if only one indicator is working on cars? umm now the bulbs in the new ones are 12/25 and the ones stated are 12/15 so im thinking perhaps they are too high a wattage?

I'm presuming they are all flashing - even if fast.
Check your grounding first.

it should be good BUT will do cheers. going to do it now
regards mmr

well ive tryed allsorts....had back inicators flashing correctly when seperate from front.......i can only think get correct wattage bulbs did try at halfords today but no joy so will get some on line .......then if puutting the 12/15 bulbs instead of the 12/25 bulbs doesnt work then at least i will have ruled that out.......ummm more head scratching then oh the joys of electics!

problem sorted!.......
i couldnt get 12/15 w bulbs the same size as aftermarket ones so i fittted a new relay to match bulbs 12/23 w
now they all flash at correct speed.
