Review: SiriusLED Extremely Bright 400 Lumens 3020 Chipset Canbus Error Free LED Bulbs for Interior Car Lights License Plate Dome Trunk - So far so good. It only has about 1 hour of intermittent service but it works well and is "very bright". I installed this in the Dometic refrigerator in our RV Camper to replace the glass tubular incandescent bulb (42mm 214-2 Festoon Bulb). The stock bulbs would burn out on every other trip. I am hoping the LED replacement will last longer. In the refrigerator, the LED lights up the entire space with a bright white light. At night, it illuminates the entire camper. The LEDs are on one side of the little circuit board and there is a heat sink on the other. This makes the lamp give off a "directional" light. The original bulbs would give off a more even "golden" colored light. There is a plastic diffuser cover in the fridge that goes over the lamp so it works out OK. Overall. I like the LED replacement. I have no way of accurately testing the 400 Lumens, but I can say that it is uncomfortable to look directly at the uncovered lamp. I call that "very bright". Some other comments say it gets hot enough to catch fire. I left the door open for about 5 minutes to see if the heat sink would get hot. It did feel slightly warm, but no where near hot enough to catch fire. It is being powered by a 12V battery. Maybe something like desertcart B00B8593GS would put off a more "even" light, but those are only rated at 240 Lumens. I am guessing they cannot produce the same output since there is no room for a heat sink. I am giving the product 5 stars for now. I will update if anything changes after a few trips.

Review: Perfect replacement for the dome lights of my 1990 325iX - The dome lights of my 1990 BMW 325iX was so dim it was like using two candles to light up the interior of the car. I replaced both of the festoon bulbs. The dome lights are so bright it is like daylight now. I wonder how I managed all those years with such dim dome lights. The festoon bulbs are of the correct length and similar in dimension girth-wise. There are some heat sinks to the back of the LEDs. So it is a bit bigger than the original bulb. My car has ample space in the light compartment. The back of the light compartment in my car is the metal roof of the car! So I am not at all concerned over heat dissipation as some other reviews suggest. If I had a choice, I would prefer the color temperature to be a bit warmer. It looks like 5000k just as the specs says. It would be better if it were 3000k. I am just glad the light output looks white and does not have a blue or purple tint to it. Overall, I am very happy with these bulbs!

## Questions & Answers

**Q: Will this bike work on my 07 dodge ram without the flickering issue?  so far every led i have purchased has that issue**
A: I'm not sure it sounds like there maybe another issue going on. LED LIGHT are very low drain did there should be no flickering.

**Q: Can the led be pointed up or down?  either pointed toward the cab or up at the reflecive surface?**
A: It's best to have the light shining down so that the heatsink is facing up for proper cooling. LED bulb components are known to get warm.

**Q: Can we use that as lighting for vw mk5 license plate?**
A: You can use them anywhere as long as it takes that size bulb.

**Q: Will this fit a 96 Chevy k1500?**

### ⭐⭐⭐⭐⭐ Super Bright, Useful and Cool to the Touch
*by C***S on February 22, 2018*

OK, I was skeptical of the amount of light touted by others in the Reviews. I installed these in my 2018 Dodge Challenger and now don't understand what I did without them. I will say that when I first installed the bulbs (without the OEM shields since they are not necessary with these cool-running bulbs) they were so bright they were almost comical. I endured the brightness for a few days and told myself I would remove them the following weekend or rotate them in their connectors to reduce at least some of the light. But I actually got accustomed to the extra light and now I would not consider changing them. In the Challenger, the driver's and the passenger map lights are close together and intended to illuminate the center console. Knowing what I know now, I am considering using one of these for the passenger side only, and then installing a red version for the driver's side. That way the driver has the option to use either white or eye-friendly red light when extra light is called for while driving or stopped -- just an idea but it makes good sense. Again, these are cool-running so OEM heat shields can be removed for best directional light.
