The Centropen Gold marker I use has a quite sharp tip. It was cheapest Gold color marker in shop but I chose it because of size of tip. Color is a bit dark but it works nice.
About lights - if You mean side lights then ring in front of light is made from copper wire, connection point was soldered and sanded, and then glued to plastic with clear Epoxy, which at the same time fills external perimeter between ring and plastic. The tricky internal parts for all lights was reflectors, actually it is very easy to make them, but hard to explain all in words (especially because my english is not very good
I'll make a picture of process later and then post a link here. And important step is good planning of gluing / filling / sanding / masking / painting sequence.
About painting - I use AK Interactive Xtreme Metal Brass color but made a mistake when choose black base instead of some light color. The black base gives good "volume" effect for surface but at the same time final color appears too dark.
If I remember correctly the painting sequence for side lights was following: some metallic color (inside of clear parts), Black primer (Vallejo), Black base (AK or Alclad), Brass (AK), Tamiya Clear, Light Grey wash (Vallejo) and finally one or two coats of Tamiya Clear.
