I didn't know my brake lever had a bulb in it.

 

Martin, did you get my payment? I Just want to be sure.

 

Hi Tommy,
you have a PM.

Best Regards
Martin

 

It hasn't.
Like I already corrected somewhere in this thread, the title regarding '328' was a mistake.
Sorry for any confusion.

Best Regards
Martin

 

Received this morning. What a great piece of work, Martin. The soldering & construction are awesome

I haven't connected it yet as my car's away from me this week. Presumably I can bench test with a 12V supply? Since LEDs are diodes am I correct that getting polarity wrong means it simply won't work? I see a warning triangle at one end of the PCB.

 

Hi Paul,

glad and somehow surprised, that you got it so fast.
Yes you can bench test it with 12V. But you can also bench test it with, for example a small 9V battery.
It contains a transistor for current sink purpose, because we have fluctuating voltage in cars and the light should work with 10V and with full alternator voltage supply. And shouldn't melt, in case of an alternator regulator failure. Say it works from 8V to 20 V and brightness does not alter with voltage.
Since it also contains a rectifier ( the biggest black part on the board ) polarity doesn't matter.
The warning triangle is to mark the fuse, which sits in the right of the warning triangle and melts in case of any shortage on the board, which is unlikely to happen since I added that epoxy on the component side.

Best Regards
Martin

 

The European postal service to & from the UK is very impressive. It's nice to see the EU functioning at maximum efficiency

Confirmed working excellently on the bench with a 9V PP3. It's dark here now and you seem to have judged the lumens output exactly right. Well done!

 

I also received my bulbs in the UK today thanks Martin. Haven't installed yet thu.

 

Hi Martin

Great work. These seem perfect and probably run a lot cooler than the original bulb which gets very hot. If you still have a spare one in green I'd be very interested?

Regards
Robert

 

Thanks Martin,

Arrived, fitted, and runs very cool... To my mind, the less current drawn/heat generated the better.

Now, to take car of all the other lights!

Best,

John.

 

Thanks John for your feedback.
Actually at 12V it draws 3,6% of current compared with the original filament bulb. (orig. bulb = 250 mAmps, LED light = 9 mAmps)
I tried each of them over 6hrs. at a 12V supply and found generated heat to be negligible.

Best Regards
Martin

 

Hi Martin,
I received my LED today and got it installed. I just want to add my appreciation here and say great job. Very nice piece of work. Thanks again,
Jeff

Do you have any green ones left?

 

Yes, I made a few more, than the exact number initially ordered.

Best Regards
Martin

 

Got them today! Thanks Martin!

Thanks to all so far for your feedback.
One week for Hongkong and West Coast US is not bad. Kudos for USPS and HK-mail.

Unfortunately I found no ESD Zip bags in yellow with a horsey

Best Regards
Martin

 

Oh, those... The originals are extremely rare and are more expensive than the LED bulbs now!

 

Actually, not as rare as you think. I was able to buy the original bulb for $5.

 

That's "cheap" for an industrial manufactured mass product.

Best Regards
Martin

 

I was not referring to the OEM bulbs, but to the "ESD Zip bags in yellow with a horsey" that Martin was talking about... (This was an attempted joke by the way)

 

Martin -

Thanks a bunch. Got my bulb today. Hope to install it this weekend when I remove the seats to have them re-done.

Thanks!

Ken

 

Just got mine today. Thanks Martin! They look good. Can't wait to try them.

 

I've tried them all just earlier. Some pictures to show the result.

I found that my original bulb is actually green with the paint melted away probably by the heat of the lit bulb.

Green LED on the car now. Thx again Martin!
