FAQ: H4 LED Bulbs

Q1: What’s the difference between H4 LED and single-beam LED bulbs?
A: H4 LED bulbs are dual-beam, meaning they combine both high and low beam functions in a single bulb socket, unlike single-beam types like H1 or H7.

Q2: Will H4 LED bulbs work with my reflector headlights?
A: Yes, H4 LED bulbs are specifically designed for reflector housings using a single bulb for high/low beam. Beam focus and alignment are important, so look for kits with optimized light pattern.

Q3: Do I need extra wiring or a relay kit for H4 LED bulbs?
A: In most cases, no. Our D-LUMINA H4 LED kits are plug-and-play. Some vehicles may benefit from a relay harness if flickering or beam switching issues occur.
