An hour?!! Was that with a 50 minute tea break in between changing bulbs? Haven't done my side lights yet but I've had a look & guess that it should take about 5 minutes a side. Hopefully I'm right, don't fancy taking the wheels off just to change a bulb & definitely not the bumper.
Possibly a 15 minute break....
Either way it wasn't what I'd call a 5 minute job personally. I just found it awkward more than anything else and not something I'd look forward to doing again.
I'm pretty handy with tool's and have got skinny arms so hopefully it won't take me too long when I get around to it. I'll make sure I set aside an hour though & some tea just in case.
