LED Indicators. The factory incandescent turn signals on the Chevrolet Silverado illuminate in a slow glow, taking a moment to turn off and on. With replacement LED bulbs, you can immediately update your vehicle with the instant on-off blinking of modern LEDs. This instant activation adds a modern and distinct look to the Silverado.

Dual Brightness. The Silverado uses a 7443 dual-filament bulb. They light up with low power as parking lights, then they get brighter when the turn signal or hazards are activated. The brightness ratio of your factory bulbs is traditionally 15:100, or 15% lumen output for the dim function. Diode Dynamics bulbs are designed to match this, so there is enough distinction between "low" and "high" brightness levels. As with all Diode Dynamics LED bulbs, these turn signal bulbs are rated with accurate, measured lumen figures, not calculations or guesses.

Switchback. The dual-filament function of your factory turn signal bulbs gives you the ability to choose a unique LED bulb model: switchback! These bulbs illuminate in a bright white for the "low" power setting for your running/parking light, then switch to intense amber when the turn signals are activated. When the turn signal is switched off, they return to the original white output. The result is a modern dual-color effect, as seen on many high-end vehicles on the road. Please note: in order to properly see the white, you must have clear reflectors/lenses over the turn signal bulb. If your Silverado has amber reflectors, you might be able to find clear aftermarket ones to complete this upgrade!

Reliability. Diode Dynamics LEDs are built with constant-current inductive circuitry, along with transient suppression. They are tested by our engineering team with a device that replicates years of voltage spikes, like the ones generated each time the alternator starts and stops on your Sierra 3500. This is what kills most LED bulbs over time, but just like factory components, Diode Dynamics LEDs are designed with built-in circuit protection. While more expensive than simple bulbs, this allows Diode Dynamics LEDs to last for years, with no flickering or failure.

Note: A set of 6 ohm resistors and connectors, to slow down hyper-blinking or prevent bulb-out warnings caused by LEDs is required.
