Diode Dynamics HP3 LED Bulbs

The Diode Dynamics HP3 LED Bulbs are designed for customers who want a compact, reliable LED upgrade for compatible mini-wedge bulb locations. These bulbs are a direct replacement for many 194, 168, 912, 921, and other T10/T15-style applications, making them a strong fit for map lights, dome lights, license plate lights, side markers, door lights, trunk lights, and other compatible interior or exterior bulb locations.

Each HP3 bulb produces 56 lumens of true measured output, providing about double the light of many original 5W 194 or 168 incandescent bulbs. Diode Dynamics uses measured lumen ratings instead of exaggerated estimates, helping customers choose a bulb based on real output performance.

The HP3 uses a single diffused optic to spread light through the original lamp housing for an OEM-style appearance and useful light distribution. Its omnidirectional 270-degree beam angle helps deliver even output whether the bulb is mounted straight into the housing or installed in a side-plug orientation.

Built for reliability, these bulbs feature constant-current circuitry, transient suppression, dual-lead contacts, and nonpolar operation. This helps reduce flicker, supports a snug socket fit, and makes installation easier in compatible bulb locations.

The HP3 lineup is available in several white and color options, including Cool White 6000K, Pure White 5000K, Natural White 4000K, Warm White 3000K, plus Blue, Red, Amber, and Green. This gives customers flexibility for interior lighting style, exterior marker applications, license plate lighting, or specialty accent use where permitted.

Whether customers are replacing dim factory interior bulbs, brightening license plate lights, refreshing side markers, or adding a cleaner LED appearance to compatible mini-wedge locations, Diode Dynamics HP3 LED Bulbs provide a proven plug-and-play lighting upgrade. Now Available at LEER!
