The following upgrade pertains to my 2012 CM ALL4 S with the Xenon headlamp assemblies.

For anyone wanting to get rid of the 'egg yolk' look with the original amber turn signal bulbs, I replaced them with Stealth Bulbs.

These bulbs have a unique chromed finish and are bright amber when activated.

The stock bulbs are 2357 and are a bay15d style meaning the pins at the base are offset (pic attached).

These bulbs perfom flawlessly and NO ERROR CODES.
