Product Description

The Diode Dynamics DD0638P SL2 LED Bulbs are a premium dual-base replacement designed to fit H11, H8, or H9 halogen sockets. Each bulb produces around 1,400 lumens at a cool white 6000K color, with a power draw of 14 watts and wide operating voltage range from 9-30V. Thanks to its fanless, passive cooling design and optimized optical alignment, these LEDs offer outstanding performance without generating excess heat or glare. Anti-flicker modules are included to minimize issues such as flickering or dashboard warnings in vehicles with sensitive electrical systems.

While suitable for fog lights, auxiliary lamps, and some applications of low or high beam (where bulb base and housing permit), DD0638P is **not universally DOT-legal** for primary headlight use in all regions. Always confirm your vehicle's bulb base type (H11/H8/H9), check housing compatibility, and verify local regulations before using as a headlight. Backed by a limited lifetime warranty, this pair is ideal for drivers looking for a reliable and bright LED upgrade.
