I fitted the switch and wiring for the spotlights a while ago but have only just got round to adding the spot lights onto the bumper brackets ……. see https://mgb.tips/?s=Spotlights

I bought some led bulbs to match the light colour of the headlights (which are LED) which simplified the wiring as I don’t need a relay as the LEDs take a lot lighter load ……. but based on recent MOT changes I may have to revert back standard bulbs and add a relay for the spots!
