Review on 12 Pack - WEIMELTOY Red LED Car Bulb 194 With 3030 Chipset & 2 SMD T10/168/W5W Wedge Light Bulbs, 1.5W 12V For License Plate, Courtesy, Step & Trunk Lamps, Clearance Lights by Jon Brazil

My 2013 Prius 3 had five of its 194 peanut bulbs burn out. These bulbs are used in multiple places on the car, including (but not limited to) the license plate illumination, inside door courtesy lights, and side marker lights in the headlight housing. All my burned bulbs were associated with the switch for parking lights and headlights.The LED bulbs look almost exactly like the peanut 194 bulbs they are replacing. Same dimensions in length and diameter. Like all LED bulbs, they are polarized, so I removed each socket containing the old bulb, swapped out the old bulb with the new LED bulb, and then turned on the parking light switch. If the LED lit up, then I turned off the light switch and reinserted the bulb/socket into its location. If the LED did not illuminate, I turned off the light switch, rotated the LED by 180°, reinserted and retested. All my LED bulbs worked properly after their polarity was successfully implemented. (In my case, all the sockets are twist-and-turn type.)The LED bulbs are much brighter than than the filament bulbs they replaced. Also a nice white light.I am very happy with these bulbs. Not sure how many of these little peanut bulbs are in my Prius, but if I need to get more, I will definitely reorder this brand.
