Hi chaps, after finally finishing my erst restoration, one of the last niggles I've got is fast indicators. Hazards are fine, but indicators are slightly too fast.

I've changed relay and fuses with no difference to eliminate them.

I've got 12v5w front and side bulbs, rears are 12v21w. Are these the correct bulbs? Obviously somehow I'm not making enough resistance for the relay...?

Googled the hell out of this but not found a fix, surely there's a solution or something I've missed that doesn't involved bodging an extra hidden bulb in? Help!

Thanks, Andy
