Has anyone fitted LED bulbs in the rear brake/tail lights? I bought some 21W/5W correct bayonet dual contact LED bulbs but the 'sidelight' wont work! Is it the LEDs do not draw enough current on tail, the bright brake seems to work OK. Testing the bulbs remotely they work both side and tail, and I have 12 v at the bulb holder when tested. I know LEDs will not work if they have positive ground (unlike a normal incandescent filament which doesn't mind which way the current flows). The bulbs are making contact with the 'lives' in the bulb holder (as witnessed by the scratch marks on the new bulb terminals). The bulbs and holders are as the top left in the diagram (BAY 15D)
