So, need some suggestions on lighting pcb install in a sd70ace. i’ve seen these installed in many ways on factory examples. The following pictures are of a sample cab and a lighting board pulled from another engine as a sample. This board has shrink tubing over part of the number board lights.

I have foil tape available for heat protection from the grain of wheat bulbs. Anyone, have a clear and clean way to install?

Should , I use heat shrink over the grain of wheat bulbs for the number boards lights on the new pcb?  I’ve seen the lights without the shrink in some samples installations. 

I know to use the heat shield tape. I’ve also seen double sided tape used to hold the number board lights in place.

I'm still trying to decide how to do this installation. My first run heat was definitely going to be a issue. I really wondering if putting a bit of shrink the new board bulbs would help. Also, have the issue of light shining down through the wind shield...

I need to find out if the number board lighting is run right off of track power on these ss 70's Maybe , the led route is the easy to go...what tends to be a good limiting resistor value. A diode perhaps in the case of going directly to track voltage.?
