The HP11 3156/3157 tail light and rear turn signal bulb set of four upgrades 2007–2013 GMC Sierra 1500 rear lighting with brighter, more modern LEDs and direct-fit installation. Each bulb uses four side-firing COB LEDs plus a top-mounted high-power chip with projector lens, housed in aluminum for full metal heatsinking and nonpolar electrical compatibility. At 310 lumens per bulb it provides more output than stock, installs plug-and-play, and includes constant-current circuitry with transient suppression for reliable, longer life.
