Replacement LED bulbs don't work

[sailabroad]

The automotive LED bulbs have the negative (return path of the circuit) connected to the ground on the car - so the outside metal part of the 1141 bulbs are wired to negative, while one of the two( sometimes both - was there any burning smell?) pins will be the positive...while in your boat it will expect one of the contact pins to be positive and one negative.

Option (1) pull apart bulb and wire + and negative to each of the contact pins as it is wired in your boat. Inside the LED s there are often very short thin wires soldered to different parts of the bulb its not too difficult to replace these and wire them as for a boat.

Option(2) pull the negative wire from the socket for the bulb and attach it to the metal part that comes in contact with the "ground" part of the bulb= the silver metal outside part.( all the sockets on my boat have this metal bit that makes contact with what would normally be the bulb s ground but yours might not)
