Possible 'oem Look' Drl Solution


Recommended Posts

Hi all,

As you might have seen in a previous post, I wanted to modify the fog light switch on the stork so that it would operate the fog lights without having any other lights on first. I don't believe this can be done without going to a skilled auto electrician and paying their high labour rates.

Sticking with the idea of using LED headlight bulbs in the OEM fog housings to run as DRLs, I found these units sold by TRS to facilitate the auto on/off control for UK MOT regulations:

Have emailed TRS for fitting advice and they said there are 3 wires on the units requiring input from my car:

1) a 12v feed from ignition (to turn on lights when car is started)

2) a ground

3) a feed from the parking/side light circuit (to turn off power when sidelights are switched on - which is UK regulation for DRLs)

Each of the above is required twice (one for each side) so am I right to be nervous to take 2x live feeds from a given ignition source?

Should I add an inline fuse?

Where would you recommend I take the live feed from so that the lights only come on when the engine is running?

Any other helpful comments are welcomed.
