The great/rubbish light debacle...

[Wouter (Retrofitlab.com)]

That's right, we've done it a lot of times. If you do not have a heatgun, you can use your oven as well. Yes I would say that for 95% of our customers it's their first time opening a headlight, and I can tell you that a lot of people have succesfully opened and retrofitted headlights which are a lot harder than this headlight. This one really is not so hard.
If you want you can also send us your headlight and we can perform the retrofit for you completely. http://www.retrofitlab.com/retrofit-service.html
