Reliable LED for license plate light
I guess the high power LED (with a metal heatsink collar on it) I bought from eBay didn't last too long on the license plate light. I think it's because they are on constantly and generate quite a bit of heat.
I'm looking at some LED's now that are made of those chip boards like this
Have you guys tried those before? I'm thinking of getting those directional ones. How reliable are the LED's that you guys have install on license plate light? Can you suggest any good places to get some good value LED's?
Thanks!

I have been using this one since they first came out...Early quality was bad, and had a burn out on one...had to return it, and then it was OK. I think it has been at least a couple of years...very bright and actually helps illuminate the rear area for backup camera (we have licence plates with white background)

Good to hear some positive reviews from these bulbs. I'm going to give another led type bulb a try, and if it doesn't work out, I'll get these!

You keep saying, "these", but you aren't posting anything.
I once paid $7 for two bulbs to come from CA instead of China. Then I bought 2 bulbs for $2 from China, and they were exactly the same. I would put money on the fact that 98% of these LEDs are made in China. (Unless they say made in USA am I am completely wrong.) None of my bulbs have burned out, and really your idea of over heating doesn't make a lot of sense. The only element in the bulb that will heat is the resistor. I bet if you opened it up, you would find a poor soldering job on that resistor that can be easily fixed. All I am saying is that I have not seen or been given any reasonable explanation why I or anyone else should spend more than $1 on an LED T10 bulb. Okay, maybe $3 if it has more than one SMD. My China cheapos have lasted since last Feb no problems, and I would bet that most bought from the USA are Chinese re-packaged and sold with a 90% profit margin.

Ummmm, for my first post, the "this" is a link. Click on it? I wish Acurazine underline the links.
And for my reply, it does seem vague, but I was referring to Chas2's link.
For some reason, the ones I bought originally were hi-power, similar to this , and it came a warning about using it for extended use. I of course ignored these warning because I knew LED's were meant for long life, or so I thought. As far as the soldering connections, they were decent. I tried to fix some by resoldering them but the LED's were just fried. (dimmed or doesn't light up) I tested the resistor using an Ohm meter, and they were in specs. The soldering job was good enough to carry the current.
As far as the heat, i'm not making the assumption that it's coming from the LED's. But it could. But the fact is, these bulbs were also installed on the door courtesy light, and they are still working from the day I installed them. Most likely a heat issue is making these LED's blow out prematurely. I will see once the lights in the door reach similar operating hours as the license plate bulb to verify if it is truly a bulb/built issue or heat.
I really do not want to spend $14 on a pair of stinking LEDs that were definitely made in China. But, if they can ensure me reliability, I just might do it, or switch back the original bulbs... http://www.ebay.com/itm/120834385078...#ht_3293wt_956 I bought these yesterday and hopefully they last longer.

Sorry, I missed the link in the first post. I don't understand what they could mean by "high power" LEDs because power assumes a voltage and a current and diodes don't drop current. Power diodes are supposed to be capable of handling high voltage and high current through them, but if that's what they meant, then these should have had no problem lasting.
None of this has to do with you; I am just confused on what they are trying to convey in their product title.
I hope you find a reliable replacement.

Of course, in this context, high power means bright.
In the first link, they are 1 W total, 60 lumens claimed. The ones I use are 2 W and claim 105 lumens. The 2 W models are noticeably brighter than various 1 W versions I have tried, a couple of which failed.
We have also had good luck with expensive Putco LEDs for a Honda Civic Si, but this car uses flank style lights.

UPDATE: I received my "Bread board" style LED's. It has 4 SMD led on it. Very small and it fits very nicely in the connector. Initial speculation is that they are a much better quality. The lights I got are whiter (4300k) than the previous "high power" ones, which had a slight blue tint (6000k).
So far, so good.
Upon inspection of the old high power led's, there seems to be some burnt marks on the LED itself, which explains the malfunction of the LED.
