There are some pics to lead you through the conversion step-by-step.
You've already changed to the popular "Clear Side Repeater Set" from ABC-Design but the front indicators have still the orange look? Why??
It's very easy to complete the conversion and less than 30 minutes are needed.
I used an oven to heaten each housing up: It's not so noisy and you can watch TV in the meantime (be warned: your next Pizza could have a 'special' taste).
A hair drier could be used also but more time is needed to heat up the whole thing.
The light bulbs I used were Philips Silver Vision. Similar lights are available from Osram ("Diadem" ).
Step_0a: the necessary parts: screwdriver, (knife), new light bulbs
Step_0b: old light bulb (left), new Philips SilverVision (right)
Step_1: put the housing into an oven (80°C, approx. 8-10 minutes) to soften the glue; then the front can be removed (be careful!)
Step_2: remove the orange cap; simply pull
Step_3: heat front glass and housing up again; put them together now
Step_4: on indicator is ready (the right on in the picture)
