New Headlights

[Stewart 38]

I have LED lights around the front grill this is fed from the relay for the radiator fan,just fitted the new GBS head lights with led side lights.I initially wired the new side lights to come on with the front led`s and then thought this would be illegal as side lights are obligatory lights and should work without the ignition on I then wired it with the sidelight switch as well but this caused feedback and when the sidelights were switched on the ignition came on.how do I stop the power feedback to the ignition

side lights dont go through a relay just a fuse they come straight from the switch on column which is also permanently live

I know side lights do not go through a relay, the feed I picked up to put the side lights on permanently I picked up from the relay

You need a pair of diodes,

One in each feed line.

Suggest 1N4001 from maplins, the white band end of each is connected together and to the side lights.

One diode is to the side light switch and the other is from the the fan relay.

A neighbour has given me some diodes he says are suitable they have markings of SKE 1/12.I cannot find the suggested maplins ones on their website

Should work.
