One of the things that I was disappointed with when I bought my ST Line X was that it didn't have standard LED rear lights unlike the Titanium X version. Didn't want to spend out on the LED headlights to get the rear ones so have bought a set of the LED type and fitted them. The inner ones in the tailgate work perfectly but the outer ones aren't. The indicator is fine since that uses a bulb anyway. But the LED brake light part sort of works although is also coming on as a side light. The proper LED strip isn't coming on at all and a bulb on the top os coming on as a side light (not sure what this bulb is for actually as the side light is meant to be the LED strip ?
Has anyone done this upgrade. Is it something that needs to be changed in the BCM or a wiring issue ?
