About H4 Bulbs & Boslla LEDs
Q: What’s special about H4 bulbs?
A: H4 bulbs are dual-beam, meaning they handle both low and high beam from a single bulb. They’re commonly found in motorcycles, trucks, and older cars with reflector housings.
Q: Do Boslla H4 LED bulbs support both beams?
A: Yes! All Boslla H4 LEDs are true dual-beam LEDs, with separate chips and beam control for accurate high/low performance.
Q: What’s the advantage of Boslla’s 3-color H4 bulbs?
A: Our 3-color H4 LEDs let you switch between:
-
6500K Cool White (normal driving)
-
4300K Warm White (rainy or foggy roads)
-
3000K Yellow (severe weather or off-road)
Perfect for adapting to changing conditions without swapping bulbs.
Q: Will these work with both reflector and projector headlights?
A: Yes, Boslla H4 LEDs are beam-optimized for both reflector and projector housings — ensuring no glare and sharp cutoffs.
Q: Is installation difficult?
A: Not at all. Our H4 bulbs are designed for plug-and-play installation, usually in under 15 minutes. No extra wiring or resistors are needed for most vehicles.
Q: Will I need a CANBUS decoder?
A: Some newer vehicles may need a CANBUS decoder to prevent flickering or error messages. Boslla offers compatible decoders if needed.
