Collection: DRL Modules: CSL Yellow, Amber & RGB

Swap the factory DRL module in each headlight for a CSL yellow module made for your model, such as the G80 M3 and G82 M4 CSL yellow DRL module. You keep your factory headlights. Pick the listing that matches your chassis code.

Yellow DRLs are best known from the BMW M4 CSL, which is where the "CSL yellow" name comes from. Our CSL yellow modules bring that look to cars such as the G80 M3, G82 M4, F30 and G20 3 Series, X5 and Z4.

It depends on where you drive. DRL color rules differ by state and country, so check your local vehicle lighting rules before you fit yellow or amber modules.

Complete kits start at $4,799.99 for the 4-door GT 50 and GT 53 carbon aero kit, and the 2-door Black Series style body kit is $19,999.99. Front lips on their own run $1,799.99 to $2,699.99.

Not by themselves. Under the Magnuson-Moss Warranty Act, a dealer has to show an aftermarket part caused a problem before refusing a claim for it, as the FTC guidance explains. Keep your receipts and the original modules.

CSL yellow and amber modules are $299.99 to $349.99, and most RGB color-changing module sets are $349.99. Orders over $99.99 qualify for free shipping.
