well im not much of a meth head but i know ablot about drugs sooo...
when it comes to lightbulbs some people like the big regular houshold ones. with those after you break out the end you need to use salt to get ALL of the white powder out of it.
i like to use the small automotive tail-light bulb. the best kind is the 1157 size, it has 2 silver things on the end that must first be broke out, leaving behind 2 small holes, use a knife or a pair or heimostats to beakout the reddish resin and then CAREFULLY use the heimo's to breakout the inside of the bulb, you have to be careful not to crack the outside bullb, there will be tiny shards of glass in the bulb left behind, use a cotton q-tip to get those out.
then get yourself a metal clip, like the ones that come off a air pressure gague, put it on a piece of antenna, and clip it to the metal and run the antenna tube into the bulb.
use small amounts of product until you learn how to melt and run your shit around the glass.
