LEDs - anyone found a good source?

LEDs certainly have gotten better. I have a couple of great products, a bicycle light and a flashlight, which are good and relatively inexpensive.

However, the LEDs which replace the 1141s and 1156s seem expensive still. Anyone know where they may be less expensive?

I bought Chinese made SMD (Surface Mount Diode) LED's off ebay. They were cheap, but about 20% had very poor tint, so I had to buy a few more to get all matching tint throughout the coach. Still way cheaper than buying from CW for $20 each. I think the Chinese ones were $3.50 for a two pack shipped.

That's the answer I wanted. Thanks a lot. I just didn't know if they could be trusted.

If 20% are bad I think you're right!

I have bought several different 12 Volt LED's on E-Bay. All were from China and All worked as advertised.
Some were not what I was expecting ,because like a Dummy, I either read the description improperly or forgot to specify the color, warmth of the LED's.
It is after all a bit of a trial and error experience and considering how little these things cost I can afford the $5 or $6 that I spent on the wrong items.

The shipping from China has gotten much better. The first ones I bought took about 1-2 months to get here. My latest purchases are down to 1-2 weeks. I was also a dummy when ordering. Didn't know the difference between cool white, soft white or what ever else the called them. Also, stay away from the long, round, acorn, 1156 type. The separate little LEDs have a tendency to burn out. Not so with the flat panel SMD type.... so far... They do come with various adapters.

I bought 5 of the surface mount type that use the little adapter extensions to go in the different type bulb sockets (none of which fit my sockets). When I got past that by making my own adapters (that didn't bother me, these were like 3.00 apiece), I found that after running them a while, they get pretty darn warm too! Not as hot as a bulb might get, but a lot hotter than I ever expected an LED might run! So later I found out that there must be resistors in the circuit to cut down the voltage to the LED from what our coaches normally supply to the light circuits.

So, lesson learned, a decent LED replacement will have something besides LEDs on the board. It'll have resistors as well.... and I haven't seen any of these for what I would consider a reasonable price yet (less than 10.00). If somebody knows a source for those that are up in the 200 lumen (brightness) range, please post!

Warm white is the level that closest duplicates a regular 12v bulb - doesn't have the blue in it.

Superbrightleds.com I'd bought 4 leds a year ago to replace our under counter lights and at 4500K they were OK for this purpose but too harsh, in my opinion, for general use. I found some 3100K units here, for about $15 each, and I really like them. They produce light in about the same color range as the halogen but not as harsh. I plan to replace most of our halogens (which keep burning out at an annoying rate) with these. I got them in about a week, if I remember correctly, from placing my order.

I'm quite familiar with LED suppliers, having used many in the past for marine projects. Here's a short list for reliability & cost considered;That should get you going, if you need more just serch for Automotive LED Lighting. Don't search marine as they charge double even though it's still 12VDC!

I bought some like this and used 4 strips to replace 2 tubes in my mini overhead florescent fixture.

Is there any danger to using SMD LED's that don't have a resisitor built into the board?

They should say they are 12 volt.

They'll work but not well, overheat and burn out. Always use resistored leds or pass external resistors if you don't.
