Lay new butyl rubber into the headlight recess
Refit the plastic lens and push into the butyl, put he headlight unit into the over for 7 mins at 130 degrees C to soften and while soft push the lens into final position. Leave to cool.
Fill any gaps with black low modulus neutral cure silicon
Install the lights into the body and wire up. Hide the DRL relay unit and wiring in the front chassis member
This particular DRL relay unit is wired this way:
A live feed was taken off the wiper motor (green/grey) on with ignition
The unit was wired into the right and left indicator circuits, the side light circuit a chassis ground and the battery positive using a 7.5amp fused connector. The DRLs take 6 amps in total normally.
And this is what they look like unilluminated..
The DRLs are illuminated when the ignition is on. They are very bright. They dim as soon as the side lights are turned on. Each side flashes with the appropriate indicator and they stay on for several seconds after remote locking.
Perfect!
