Went ahead and ordered the 8 dollar bulb. I googleed the Neo Wedge bulb and they seem to all be LED. In past experiences I noticed if you swap to LED you gotta swap all the bulbs so they match. If anymore burn out ill look into them more
I think replacing just the ATC bulbs with LEDs would've matched the rest of the dash Illumination. The bulbs are clear so use white LEDs. Is it 3 or 4 bulbs in the ATC? Can't remember. The green color comes from the tinted plastic the bulbs sit behind.
You could also look around for a used EVIC or OTIS at the yards. They use the same bulbs and holders.
