I have seen several people do these ZHP lighted mods. All either have glue showing or light leaking around the edges. The way I did it, with the trimmed down black ring (
A) that fits snuggly inside the modified ZHP, it seals the light from escaping around the edges and also gives the lighted shift pattern a place to rest without any glue necessary. The biggest benefit I see with doing this yourself is, if you wanted to go back to stock, all you have to do is order a new one-peice OEM shift/boot and just pulg it back in. Another big benefit that was important to me was to use the stock LED board. The stock LED has 6 tiny LED's which provides an EVEN distribution of light over the entire pattern. Some of the aftermaket LEDs are bulky and maybe only use 2 LED's.
