The 10-diode, 4-in. round Smart Lamp LED light models are SAE J845 Class 2 compliant and DOT approved. Peterson’s strobing LED warning lamps can be integrated into new vehicles or retrofitted to existing ones. The lamp has built-in electronic strobe and turn signal functions, and keeps the lights strobe in synch. The new 10-diode models feature a triple-flash strobe that can be manually activated or configured for automatic strobing when the vehicle is shifted into reverse. Activating the turn signal automatically overrides the alternating strobe function. The 10-diode models are available in two series. Both models fit standard 4-in. mounting grommets, and the 9-32 volt operating range works on 12- and 24-volt systems.
Affected trucks include model year 2008-2018 Freightliner Cascadia and Western Star 4700, 4900, 5700 and 6900 trucks. DTNA says after hard brake applications, the brake light pressure switch may not activate the brake lights with the light application of the brake pedal.
