Jtech 10x T10 194 168 2825 W5W Super Bright White LED Bulb Car Interior Dome Map Door Courtesy License Plate Light

These LED's can replace sizes 158 (bright), 194 (brighter) and 168 (brightest) bulbs however I found the stock 168 bulb to be brighter than these LED's despite giving off a yellow hue compared to the cooler temperature LED's.These lights are great for dash, instrument panel and interior illumination. They have the slightest tint of blue, most likely in between the 6000K to 8000K range when compared to the hue of HID's. They are by no means ultra bright like many LED's that are significantly more expensive so don't be disappointed when they don't light up your car like daylight - you get what you pay for, but in this case, I think you definitely get your money's worth.Two of my dash bulbs in my 1995 Infinity G20 burned out and one of my instrument panels had been dark for awhile so I sacrificed a Saturday to strip my car apart to get at all the bulbs. It was quite the endeavor but well worth it. Look for my pictures to see comparisons of before and after. I used a combination of these 5-SMD LED's and  8x T10 194 168 501 4-smd 3528 LED Car Light Bulb White  to compare the output but did not notice a difference. I concluded behind any panel, the light output was negligible between the two. However, in open spaces like trunks, door step lights and dome lights, these omnidirectional LED's performed much better.One of my secondary headlight bulbs had also burned out so I tested one of these LED lights there as well. Again, both the 4-SMD directional LED's and these 5-SMD omnidirectional LED's looked the same. Unfortunately, next to my  Sylvania 9004 SU SilverStar Ultra Halogen Headlight Bulb (Low/High Beam), (Pack of 2)  which are around 4300K and have a yellowish tint, it looked very blue due to the stark contrast in temperature. From far away though, it wasn't as noticeable as the pictures make them out to be and since these bulbs cost significantly less than a filament bulb, I left it in. I changed out my girlfriends 2008 Honda Accord's door lights as well and they looked fantastic.None of the bulbs I received were defective. If you have any problems with the lights flickering or not making good contact, I would suggest bending the wires outward at the base of the lights to provide better connectivity.

Bought these to replace my interior lighting and also the license plate lighting on my vehicle. The light is a very "cool-white," and looks much better and more appealing. It creates a different mood in the car to a more modern look from the yellow and dull looking incandescent that it replaced. Unfortunately, these are dimmer than the incandescent bulbs (type 168) that were placed, but they are still bright enough. For whatever reason in my vehicle, the LEDs became much brighter when I manually turn on my interior lighting in the car.They are well worth the money, especially for the value. Would definitely recommend to a friend.1 of the 10 bulbs was apparently damaged. Each bulb has 5 LEDs on it and one of the LEDs had been damaged, thus causing that one LED to flicker and look very dull, creating a bluish-yellow light instead of a completely bluish-white light. No problem though since it came in a pack of 10 and I had two left.UPDATE:I figured out that the dimness was caused by a blown fuse when I was switching out the incandescent bulbs to LEDs. This was due to me checking the polarity of the LEDs as I had to make sure the lights turned on before putting everything back together. After replacing the blown fuse, my entire interior was lit up like it was daytime. I have added a picture in the customer reviews, unfortunately I do not have any before photos.

OVERALL THOUGHTS:Not as bright as others I had/ have, but a this price (currently under $10 for 10 bulbs)you can't beat this value. The best ones I have are from LEDMOD_DOT_COM and were $5 for a pair. The LEDS I bought here from JTECHnow are only maybe 10% dimmer than the super bright ones I own. Most buyers will not notice this and if you use them in pairs, should not have any issues. Some quailty issues were noticed, but they did not keep the LED bulbs from working. I will be buying more of these from Amazon and this seller over the other brighter ones I have.WHAT I GOT: (See my image for reference)The bulbs come in an easy to open display packaging. Mine were neatly organized and had a small foam layer behind them that kept them from rattling. The entire package was then placed in an padded envelope. Not the best packaging for shipping but it arrived safely.QUALITY INSPECTION: (See my image for reference)The LED's looked very nice. All were clean and free of residue from solder or other films from the manufacturing process. I did notice on two of the LED assembly's that they were made at an odd angle. This might affect use if the tolerance is tight for your application, but not for me. (See my image for reference.)I could not notice any cold solder joints and all solder looked shiny and clean with good contact. On a scale of 1 to 10, I give the solder job on these a solid 8. I tried a light twist test to see if the circuits would easily break off the plastic base, but they seemed well enough secure. Your not going to have any twisting forces when inserting or removing these bulbs.TESTING: (See my image for reference)My testing was semi scientific as I used a DC power supply with 3VDC, 4.4VDC,6VDC, 7.5VDC,9VDC and 12VDC. Each were tested at 7.5VDC, 9VDC and 12VDC. (I could not get them to light on any voltage lower then the 7.5VDC setting of my supply.) I did this to verify that each worked, and to verify if they are polarity sensitive (they ARE) and to note which side is the positive and negative for later use. At 7.5VDC the LEDS lit up. You could see each individual segment clearly.(each LED assembly has 3 light emmitting segments) At 9VDC you can not look at them without hurting your eyes. The LEDS were bright and full. 12VDC was full brightness and blinding after just glancing at them quickly. Within seconds I felt like I was looking into a camera flash. Unfortunately this was hard to photograph, because the varying output would affect my camera's focus and apeture. The higher the voltage, the darker the background seemed. I did manage to get a few decent pictures for reference. All the bulbs were left running for about 5 minutes before removing from my test jig. All bulbs appeared to have the same color (PURE WHITE) and all were the same intensity, to my naked (and somewhat blinded) eye.PRACTICAL USE: (See my image for reference)I bought these to use in my restored 1995 Celica. I had replaced the head lights with JDM ones from Japan. The stock 194 bulbs would illuminate the "City Lights" (small white marker lights within the headlights themselves) with a dim, yellow hue. The LED's fit right in the OEM socket, as snug as the original bulbs did and were a nice BRIGHT WHITE. I regret I did not take a picture with one 194 bulb and one LED bulb for a 'side by side' comparison, but I did get a decent shot of the white light within' the headlight.PROS:*Very bright white color*Uniform color & brightness from one LED to the next*EXCEPTOINAL value at less than $1 each. (including shipping!)*High quality construction & materials (rival or equals the more expesive LED's I have)*OEM fit into bulb socket (at least on Toyota Celica's!)*Easy open package that cam be reused to store unused LED bulbsCONS:*Some assembly issues/ quality control*Packaging material a bit weak in my opinion. (Shipped in a padded envelope)*Can't find out what warranty is (90 day? 6 months? 1 year?)CLOSING: I hope to update this review wth a longevity report and if I have any issues. As of right now (10-9-13) I and extremely satisfied with this purchace and the seller "JTECHnow", but I reserve the right to change that if they turn out to be duds!
