Junior's car, a 2017 vw golf.
Wipers: 10 mins.
Wing mirror glass: 10 mins.
Headlight bulb: 5 hours.
As with most modern cars, the production line starts with the headlight bulbs suspended on stalks, and they build the rest of the car around them.
Watched a few videos about how to proceed, and all of them are wrong.
None of them match what I actually have here.
Probably due to the vids being US or Euro in origin, and the cars are subtly different.
The bulbs can actually be removed,*just*, in-situ.
You just pop off a rubber cover, and then twist the lampholder anti-clockwise, and out they come.
But there is only marginal clearance behind the headlight to easily get them out to a position where you can actually swap the bulb. Takes a couple of minutes finagling it out.
The problem arises trying to re-fit the lampholder into the headlight assembly, totally blind.
You just can't see in the back of the headlight unit, there's no line-of-sight.
It has to be done by blind groping and peering in the front.
The instructions have you dismantle the whole front of the car to pull the headlight unit forward out of the car to help with this.
I tried this, but the instructions were just wrong.
After un-doing all the fixings, the headlight unit became quite free, but could not be slid out forward like the videos showed.
There was a substantial plastic peg sat under the lower part of the front bumper, which prevented forward movement.
I was unable to remove the bumper panel at this point, and gave up.
Resorted to blind groping which eventually worked.
Note to self: When removing lamp, note the orientation of the twisty handle of the lampholder when in locked-in mode, and note the position when it comes loose, so you can estimate the correct orientation when trying to re-fit blind!
