Mercedes owners, these iJDMTOY LED courtesy lights are such a cool upgrade for your CLA or CLS Class! They replace your factory side door step lights with super bright white LED illumination that's at least three times brighter than the stock bulbs. Each light assembly is powered by 18 individual 3W SMD LED diodes, so the light output is seriously impressive and gives your car that modern, luxury appearance. The installation is direct plug-and-play - they're designed to replace OEM part numbers A0028201401/A002-820-1401 and fit right into the existing housing without any modifications needed. They work with the factory 168, 194, or 6418 C5W bulb sockets and include CAN-bus error free decoders so you won't get any warning lights on your dashboard. The clear lens provides a clean, sharp light pattern that looks fantastic when the doors are open. Not only do they look amazing, but they actually improve safety at night by illuminating the ground around your doors much better than the dim factory lights. Compatible with 2014-up CLA-Class and 2011-2017 CLS-Class models. It's one of those simple upgrades that makes a huge difference in how premium your vehicle feels. Definitely gives your Mercedes that custom, high-end look without breaking the bank!
