Looking for some help with my ILS bars... I'm having some issues with a couple of the heads not lighting up and all and one that likes to light up when it wants...

This is the style I have (pre Spectra-LUX, Solaris-esque style boards)

Drivers side front bar 1st "flat" head from the center. I can't get it to light no matter what I try...

Drivers side rear bar, second from center I can't get to light. And the second one in from the end likes to lights sometimes and then go out...

I'm not very familiar with these, so any help would be appreciated...

Thanks guys and gals!!!

ILS boards along with those from Arjents and legends are notorious for halving bad solder connections. The problem was federal coated and sealed the board making them impossible to fix. Since they don't have individual modules the only way to fix it is to replace the whole board. The MOSHP had a ton of these in use, until the modules started going out and couldn't be repaired. Now all ILB are whelen. If someone else out there has more info that would be great, I have a stack of about 30 boards from legends that all have a single module or two out.

This.

Almost all our legends have a board or two out. If you’re good with soldering you can probably fix it, but it’s no simple task
