Review on Philips 194WLED Ultinon LED Bulb (White) by John Miranda

Very good LED replacement for the 194 white bulb. BUT the bulbs were causing a "license plate lights off" message on the DIC on my 2015 RAM 3500 truck. The error message is automatically deleted and I'm curious to see if it comes back. It appears that the appropriate computer must monitor this circuit for either the correct bulb filament resistance or the appropriate current drawn. Also, this 194 LED light is noticeably brighter and much whiter than the 194 incandescent bulbs it replaces without being overly bright. Also bought a red and amber color for the side marker lights with red and amber lenses, worked great. A NOTICE. "Yellow" LEDs are yellow rather than amber. Good for amber lens marker lights, but bad for clear top lens marker lights fitted with 194NA (natural amber) filament bulbs. The LED upgrade is suitable for rear and side marker lights with red and amber lenses and white license plate lights. Stick to natural amber bulbs for the marker lights on the roof.
