LED Sidemarkers for 2014-2019 Cadillac CTS (non V) (pair)

The Diode Dynamics LED Sidemarkers for the Cadillac CTS are a direct-fit replacement that upgrades your factory amber sidemarkers to crisp, bright LED output for improved side visibility and a cleaner look.

Unlike generic aftermarket options, these sidemarkers are engineered specifically for your CTS, using a vehicle-specific mounting bracket that drops into the factory location without modification. The result is a factory-quality fit with noticeably better illumination compared to the dim incandescent bulbs your car left the dealership with.

These are a smart upgrade whether you want sharper visibility for other drivers, a more modern appearance on your Cadillac, or simply a longer-lasting alternative to bulbs that burn out and need constant replacement. The sealed assembly keeps moisture and road grime out, so once they're in, you can count on them to perform reliably through Canadian winters and everything else the road throws at your car.
