The Serundo 31mm LED Festoon is the perfect way to ditch those dim, yellowish factory bulbs. It’s a tiny change that makes a huge difference in visibility and style. The Best Parts: Crisp Lighting: The 6000K white light makes the interior look modern and much cleaner than halogens. Perfect Fit: At exactly 31mm (1.22in), it snapped right into the housing with no rattling or loose connections. Powerful Output: It’s bright enough to actually find things on the floor at night without being blinding. Solid Build: The heat sink design feels durable, and I haven't noticed any flickering or "ghosting." Bottom Line: An affordable, 5-minute install that completely refreshes your car’s interior. Definitely worth it!

Extremely bright LED Bulb, so bright it's blinding. I installed these in my 2018 Dodge Challenger interior lights and I had to squeeze the contacts a bit, because these bulbs are slightly thinner than the original ones. No polarity issues, works great.

Install was very easy. They replaced my old bulbs just fine and are very bright.
