JOYCOURT 30Pack 194 Car LED Light Bulbs, 0.36W 12V T10 6000K Interior Lights, 168 2825 W5W Wedge COB LED Replacement Bulbs, Universal Dashboard Light, Dome Light, Sign Light, License Plate Light

Single polarity design, whatever. If you'll plug the lamp and it won't work, so change it's polarity. Low heating and low power consumption LED lamps. The dimensions are exactly the same with the classic halogen W5W lamp. It has no flickering effect, I've checked it by the cellphone camera. The brightness intensivety much higher, than typical halogen lamp has, BUT! The heating parameter is "almost not present", that's ideal IMO - a first point. The second - is the lowest current flow i ever seen with LEDs: 0.018A [0.018A*12,7V ≈ 0.23W-0.25W]. Such low consumption confirms (and explains) low heat as well. While a typical halogen W5W-type lamp "takes" 0.358A [0.358A*12,7V ≈ 4,6W / 13,7V*0.358A ≈ 5W] and it heats as an "oven"! So, the LED I've selected got nice warm-yellow color, eyes friendly (3000K i guess). It's even color-warmer (orange-closer), than the regular halogen lamp, check the images. The bulb got crystal acrylic cast design, that is totally isolated out of water or dust (exclude a contacts ofcause). It provides shade-less 360⁰ all-around illumination, that's matches with a halogen bulb mostly. I believe, such LEDs will last for a long. I got no idea about power stabilization system of this LEDs. If they supports only direct 12v or 14v DC, means they can burn out fast being connected upon engine start (for example). Actually this is (an inegrated current stabilization) is the unique point how such bulbs could brake down, IMO. Well, there is one bad point under all of that. The LED's contacts basement is bolder, than the halogen lamp has. I've inserted them into the same socket instead of my W5W lamps. The LEDs entered without damaging a socket, but so much tight, that i thought it'll brake something. Abnormal tight, but fits. 5+ stars. +Indestructible design. +Low price 5,3$ / 30pcs. +Ultra-low heat ability. +Ultra-low power consumption. +1:1 size ratio match to native W5W halogen. +Close-to-halogen surround illumination. +Anyway much brighter, than halogen. -thicker base, which might damage a socket.

★★★★★ Excellent Quality at a Great Price! These LED light bulbs are a fantastic find—much cheaper than anything you’d get at the auto parts store, but the quality is just as good, if not better. Bright, clear light and easy installation. I’ve had zero issues, and they’ve made a noticeable difference. Highly recommend if you’re looking to save money without sacrificing performance!

Just great, color is great easy install

Great price for how many you get, however they are not the highest quality. The contact strips are a bit too wide and make plugging them in very difficult. You have to press them in very hard. They are bright and provide much more light.

Very good quality lights and for a great price

Good price fast shipping excellent seller

The item was delivered in good condition and now I am going to try them out

I was looking to convert all of my vehicles light bulbs into LED, so I started shopping around online to see what the prices were of them, and the quality.. So I found this brand and let me tell you, I am so damn happy and pleased to have found this brand and the price is not even touchable.. I recommend this brand to anyone that wants bright lights.
