Original BMW electronics box 63-11-7-180-829 is the uncoded ALC module that manages headlight functions on the 2008–2013 BMW 128i and 135i, the 2013 135is, the 2011 1 Series M, and the 2012–2015 X1. A headlight control module communicates with the car's sensors, switches, and other control units. Modules of this type handle jobs such as automatic headlight switching, daytime running lights, beam leveling, and adaptive or cornering lights. BMW supplies this unit uncoded. It is made in Spain and weighs 190 g (0.4 lb).

As an Original BMW part, this module comes with a 24-month parts warranty.

One module number covers a wide range of engines in these cars. BMW's parts data shows it in these applications:

• 128i with the N52N and N51
• 135i with the N54 and N55
• 1 Series M Coupe with the N54T
• X1 with the N20, N52N, and N55

These cars are built on the E82 and E88 1 Series and the E84 X1. BMW lists the same module number across these engines. BMW's parts data shows the module in production from September 2005, so the same unit stayed in use across the full run of these models.
