Hi.  I make mistake and try to put leds indicators on.  Its works first few h,  but when i stop after few min was sound like little bang.  I check fuse and it was good.  I put back old ones and still not working. I cheack relay and didnt any damage. Can you please help me? I think its relay but maybe something else? And what i need to do tu put led indicators? What i need to by or change? Cheers

LED indicators often require a different relay. Usually just a few quid from Maplins or something.

Not up on the exact details myself, but either someone will advise, or you can have a Google and see what turns up.
