Review: Small Bulb, Massive Upgrade! - ​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!
Review: Works great in a 2003 Tundra. - Install was very easy. They replaced my old bulbs just fine and are very bright.
