Special design for older cars. 1158 with a BA15D base and two brightness levels for positive or negative chassis cars. The life is up to 30,000 hours. Available in white 6000 Kelvin, warm white 3000 Kelvin, Red 625 nm Green 526 nm, Blue 464 nm& Yellow 594 nm. Available 1158 BA15D. Great bulb for tight fit, this small high power led is great for all applications, very bright 260 lumen output in 360 degree illumination. This bulb will operate in classic old cars with positive chassis or negative chassis car or bike, low voltage. Comparable to a 25 watt incandescent, very small fits it tight bulb locations. CE and Rohs listed. Works good for navigation lights for its small profile, operates both AC or DC. Each 5730 chip is the latest in high power SMD technologies. Each 5730 SMD ship can dissipates up to 1/2 watt of power. The light output from a 5730 SMD is about 40 to 60 lumen output per LED chip. The LED bulb is dimmable by a variable AC or DC up to 6 volts.
