Diode Dynamics Amber Front Turn Signal LED Light Bulbs; 7443 HP48

Product Overview. These LED front turn signal bulbs provide an upgrade over factory incandescent bulbs, delivering instant on/off LED lighting with brighter output for improved visibility and a modern, refined look. Designed as a direct replacement for 7443 dual-filament bulbs on Chevrolet Silverado trucks, these bulbs enhance signal responsiveness and the vehicle’s front lighting appearance.

Construction and Appearance. Featuring high-quality components, the bulbs include constant-current inductive circuitry and built-in transient suppression to protect against voltage spikes. They come in the 7443 OEM-size form factor for plug-and-play installation without modification. The amber color ensures clear, vivid signaling, while switchback variants offer bright white light for parking functions and amber for turn signals.

Installation. Installation requires no drilling or vehicle modification and typically takes 30 to 60 minutes with basic tools. Because of the low power draw of LEDs, 6-ohm load resistors must be added to the turn signal circuit to prevent hyperblinking; this involves simple wiring taps at the turn signal sockets.

Warranty. These bulbs come with a 3-year limited replacement warranty for reliable performance and customer satisfaction.

Application. Designed specifically for the 14-26 Silverado 2500 HD, this product fits without compatibility issues and offers an effective upgrade to factory front turn signals.
