Hey BMW owners! Want to give your ride that fresh M4-inspired front end look? These MODIPIM LED angel eyes are exactly what you need. They're specifically designed to fit BMW 2, 3, 4, and 5 series models, and let me tell you - they look absolutely killer installed. The coolest part? They've got this smart switchback feature where they shine brilliant white as your daytime running lights, but when you hit your turn signal, they flash amber yellow then switch right back to white. How awesome is that? Each set comes with 4 pieces of these dual-color circuit boards packed with 540 SMD LED diodes total, so you're getting serious brightness here. Now, full disclosure - installation isn't exactly plug-and-play. You'll need to do some headlight mods which might include baking open your headlamps, some cutting, drilling, and possibly adding brackets. That's why we strongly recommend getting these professionally installed unless you're really comfortable with automotive electrical work. But trust me, the final result is totally worth it - that sharp, aggressive M4 style that'll make your BMW stand out from the crowd. The kit includes everything you need: all four M4 iconic style LED rings plus the relay wiring harness. Got questions? We're here to help regardless of your warranty status - just reach out!
