I installed some aftermarket LED replacement bulbs for my indicators and as expected they caused the flasher to run too fast. Is there anyway to make them flash at normal speed?

Thanks,
Michael

PS I have searched but could only find other's asking the same question but no answers.

You replaced your blubs with something that uses less power than the stock bulb; you need to add a resistor that simulates the led+"old bulb" or change the thermal flasher!

Thanks for the reply. I considered adding a dummy load but it would have to be quite high. I'd need to have a 20watt resistor which are quite chunky. I tested with 10W and it was not enough, slowing it down a bit but still not enough. Can you get the flashers in different values or can you get ones that are not dependant on load?

add more caps to the flasher unit. its located near the clutch pedal. there are 2 or 3 electrolytic caps in the timing circuit, 2 of them need to be approximately doubled in value (10uf). play around with the values until you get a speed you like.

MikeC

There are 3 caps with these values:

C1 22uF 25V electrolytic
C2 3.3uF 50V electrolytic
C3 10uF

C3 doesn't show a voltage and looks like it's not electrolytic. Do you know which 2 should be changed and approx what value?

Thanks for the info

like I said you have to play with it since the rate depends on the load on the flasher. I think I added 10 or 15uf to mine by soldering another cap on the back of the board across the originals. Oh and on my car only the front signals are LED so if you have front and rear LEDs you will need a larger value.

ok, thanks. I tried a 10uF across both the electrolytics because that's all I had and neither made any difference. I did only do one at a time so I'll try soldering a 10uF to each and see what happens.
