Pingu when you say scars do you mean the fitting or regret having done the job?
The scars are on the backs of my hands and caused by the limited access inside the fuse box.
I wouldn't do it again. It was a lot of effort for not a lot of reward.
At the time, the only cars with DRLs were Swedish, so there were lots of "You've got your lights on" comments.
If I were to do it again, I would investigate just having the front sidelights on. That would mean disconnecting the front and rear sidelight circuits, but being able to reconnect them when I want side and tail to be on.
