Philips Automotive Lighting7443RLED Ultinon LED Replacement Bulb for Stop and Tail Lights, Bright Red, 2 Pack

Having an EE Background I know that dc light emitting diodes(led) are required to be correctly polarized (positive and ground) for it emit light but I missed that step and thought I got 2 defective lights. My number one suggestion is once you have placed these in the socket make sure they work before reinstalling the socket into the light fixture. If it doesn’t work pull the bulb straight out of the socket rotate it 180 degrees (turn it upside down) and reinsert the bulb and check again. Overall I am happy to never have to replace this bulb again because it is a pain in the butt to get to and it will out last the beater it is installed in. It is bright enough to see in the day but unfortunately isn’t bright enough to wake up the distracted driver behind you, but then again I don’t think any street legal bulb could do that.

Great product. Works great.

Do not function as true 7443 dual function. Was no difference in brightness from running to brake. Brake did function on its own but these are actually dimmer than the standard filament bulbs. I'm disappointed that such a reputable company would make such trash.

Bought the red led lights to replace a burned out taillight and turn signal. If you just need these as your taillights and brake lights you might be fine, they looked good and were bright, buy not as bright as the halogen they were replacing. The problem was with them also functioning as the turn signal bulbs. My car did NOT recognize them and would flash them as if one was burned out. They worked but the car did not "sense" them due to the lack of resistance from them being LED and not a normal bulb.

I bought 1 set for my Scion xA, which worked nice. That one was with 6 leds each on 3 sides of the bulb, which was very bright at daytime when on the brakes. Bought a second set a year later, but got the new style with only 4 leds in the top under a red dome. With the lights on, I hardly see a difference when I apply the brakes. Wish Philips had used a different number for the new style and still make the old one.

I ordered this without noticing the online reviews that cautioned against replacing incandescent bulbs with LED lights. So I was a little apprehensive about the bulbs not working properly in my 2015 Camry LE (either hyperblinking or giving a console error). Neither of them happened. Another plus in my book (or minus for others) is that the lights are not much stronger than the original incandescents, so they shouldn't bother the other drivers. However, their hue is different from the incadescents (which are more yellowish), hence one has to replace both tail lights, even if only one is burnt out.Very easy to replace on the Camry, just google the video about it. The one thing I would do differently though, next time, is to buy a long-life version. Although I am sure even this one will last much longer than the 25,000 miles the incandescent lasted.

Didn’t work for both brake lights and driving night light. It only worked as the night driving light OR brake light. NOT both. I even flipped 180 thinking it may be the polarity. This was in a ‘13 Impreza.

Philips quality is better than most other brands - this item is no exception. I had installed a quality aftermarket red LED unit for my brake lights about 10 years ago which were much larger and had leds in every direction. That setup was functional but unfortunately projected light which is not needed for brake lights. The Philips setup does not project light out, but illuminates the brake light housing (much easier on the eyes for other drivers). Also these bulbs are a little smaller in size than the typical current aftermarket LED units. Again, if you want a projecting right light, do not purchase these, but for illumination of a housing, these are perfect.
