Warning light is dim after fitting led indicators.

[QUOTE=spuggy;578274]I'd swap the stock flasher relay back in temporarily and see how bright the tell-tale bulb was then. I suspect this may be the issue, but have no idea why. Diagnosing is key, though...

Was going to suggest that you swap the old relay back.

It sounds like the flasher may be restricting the voltage and/or current available to the whole indicator circuit - and thus the tell-tale bulb - somehow. The LEDs are probably more tolerant of lower voltage and won't care, but a voltmeter would make it pretty obvious. If that's true, then a higher-wattage bulb likely won't make any difference. Perhaps the relay is in some way incorrect or faulty?

I'm guessing too that the LED relay you have has ballast resistors built in which would explain the dull bulb if that is in the same circuit.
