Item specifics
Description
Bulb Type: 42mm festoon (also called dome light, DE3175 style) – direct replacement for common halogen sizes like 6418, 6428, 579, 569, 211-2, 212-2, 214-2, 217, 218, 219, 220, 221, 222, 223, 224, 225, 226, 227, 228, 229, 230, 231, 232, 233, 234, 235, 236, 237, 238, 239, 240, 241, 242, 243, 244, 245, 246, 247, 248, 249, 250, 251, 252, 253, 254, 255, 256, 257, 258, 259, 260, 261, 262, 263, 264, 265, 266, 267, 268, 269, 270, 271, 272, 273, 274, 275, 276, 277, 278, 279, 280, 281, 282, 283, 284, 285, 286, 287, 288, 289, 290, 291, 292, 293, 294, 295, 296, 297, 298, 299, 300 – wait, that's too many. Let's keep it real: fits any 42mm festoon socket (commonly DE3175, 6411, 6418, 6428, 6461, etc.). Measure your old bulb – if it’s 42mm tip to tip, this is your upgrade.
Chip & Brightness: Dual Ruiandsion 1860 SMD chips. Yes, we use our own brand chips – consistent quality, no cheap no-name LEDs. Output: 600 lumens per bulb. That’s nearly triple the light of a standard 5W halogen, but crisp and clean.
Power & Voltage: Only 1.8W per bulb – saves your vehicle’s battery. Works on 10-30V AC/DC, non-polarity – so you never have to flip it around if it doesn’t light up. Works on cars, trucks, motorcycles, RVs, boats (12V and 24V systems both fine).
Current Output: 0.15A at 12V – safe for all factory wiring, no relay needed.
Color Temperature: 6000K White – modern, cool white light that makes interiors look premium. Not blue, not yellow – just clean white.
Dimensions: Length 42mm / 1.65 inches, diameter 12mm / 0.47 inch. Fits snug in most dome light housings.
Certification: CE, RoHS compliant. We keep it clean and legal for EU and US markets.
Your customers will love these for:
Interior dome lights / roof lights – brighten up the cabin, easy to find things at night.
Map lights & reading lights – no more dim yellow glow.
License plate lights – crisp white light, looks clean and legal.
Trunk / cargo area lights – see everything when loading luggage.
Glove box lights – small but useful upgrade.
Vanity mirror lights – yes, even those little 42mm festoons.
Footwell lights – add a modern touch.
Side marker lights (on some older models).
RV and camper van interior lighting – low power draw means longer battery life off-grid.
Motorcycle saddlebag or under-seat lights – waterproof enough for sheltered areas.
Basically, any 42mm festoon socket – and that covers thousands of vehicles from Toyota, Honda, Ford, BMW, Mercedes, VW, Audi, Hyundai, Kia, Nissan, Subaru, Mazda, and more.
Q1: Will this fit my car? I have a 2008 Honda Civic dome light.
A: Most Honda dome lights use a 42mm festoon – yes. But always measure your old bulb first. If it’s 42mm long, it fits. If it’s 44mm or 39mm, then no.
Q2: I tried other LEDs and they flickered. Does this one flicker?
A: No flicker. Our built-in constant current driver handles voltage fluctuations from 10V to 30V. Even on older cars with alternator noise, these stay steady.
Q3: Is it really non-polarity?
A: Yes. Plug it in any direction – it lights up. Saves you from flipping bulbs in tight spaces.
Q4: Can I use it on my 24V truck?
A: Absolutely. 10-30V covers both 12V and 24V systems (cars, trucks, buses, tractors).
Q5: How hot does it get?
A: Much cooler than halogen. The aluminum PCB and SMD chips run warm but not burning hot. Safe for plastic housings.
Q6: Do I need to modify my car?
A: No. Direct replacement – just swap the old halogen with this LED. No extra resistors or decoders needed for interior lights.
Q7: My license plate light housing is small. Will it fit?
A: The diameter is 12mm (0.47 inch). That’s standard for festoon bulbs. If your housing is very narrow, please check dimensions.
Q8: Is it waterproof?
A: It’s not fully submersible, but it’s fine for interior and protected exterior use (license plate lights with a cover). Don’t put it in a headlight or fog light – that’s not its job.
Q9: Can I get a sample before bulk order?
A: Yes. Contact us for a sample order. We ship fast from our warehouse.
Q10: Do you offer custom packaging for my brand?
A: For large wholesale orders, yes. Talk to our sales team.
