The Diode Dynamics HP48 LED Bulbs are designed for customers who want to replace yellowish factory incandescent bulbs with a cleaner, modern LED appearance. These bulbs are a strong fit for compatible fog light, daytime running light, and select exterior lighting applications where a cool white cosmetic upgrade is desired.
Each HP48 bulb is populated with 48 Epistar 3014 LED chips and produces 250 measured lumens. Diode Dynamics notes that the HP48 is a cosmetic upgrade designed to provide similar output to the factory bulb while delivering a more modern 6000K cool white appearance.
The HP48 design uses a cap on the top of the bulb to direct light backward and away from the bulb rather than straight out. This helps the light spread more uniformly through the factory housing and supports a smoother appearance in compatible fog light or DRL locations.
Built for reliability, HP48 bulbs feature constant-current circuitry and transient suppression, helping reduce flicker and electrical stress compared with lower-quality LED replacement bulbs. Select HP48 configurations are listed with 9–16V operation, 270-degree omnidirectional beam angle, and a wide operating temperature range of -40°F to 185°F.
The HP48 lineup includes common forward-lighting bulb sizes such as H8, H11, H10 / 9145, and additional socket options depending on vehicle application. Diode Dynamics specifically notes that HP48 bulbs are best used as a fog light or DRL cosmetic upgrade and should not be used in low beam or high beam headlight applications.
Whether customers are refreshing fog lights, upgrading DRL appearance, or replacing compatible yellow incandescent bulbs with a crisp cool white look, Diode Dynamics HP48 LED Bulbs provide a simple plug-and-play lighting upgrade. Now Available at LEER!
