Do these bolt directly to the factory mounting points?

Yes. These mount at the OEM headlight locations—no drilling or fabrication required. You'll remove the old housings and install these in their place using existing fastener points.

Will I need to reprogram or code the sequential turn signals?

The sequential function is built into the LED modules themselves. Some buyers have reported needing to run a CAN-bus coding update through BMW's iDrive system to activate the feature fully—check with your BMW specialist to confirm what your specific model year requires.

What if one of the LED halos or turn signal modules fails after installation?

Contact ModSupply support with your order number and photos of the issue. Defective modules may be eligible for replacement depending on the failure cause and how long you've owned them. Keep your original packaging for returns.
