I've replaced 11 of 14 bulbs in the van with Led's. The last 3 are giving me a problem.
The 3 existing bulbs are what I'd call car side light bulbs...central positive terminal with 2 small lugs on opposite sides of the body that are the negative (earth) terminal.
When I put the leds in these fittings they don't light up, but they do if I put them across the battery terminals. On testing the existing fittings, the central terminal, normally wired positive, is wired negative...and I'm sure that the existing car bulbs in those fittings are not polarity sensitive.
Is it a simple case of snipping the wiring in the fittings, connecting them the 'other way' and that will be ok, or will it affect other stuff on the lighting circuit ?
All internal lights are on the one circuit.
