Reply to "A Handy Little PCB for Adding Marker LEDs to a Hood Diesel"

I had a request from a gentleman wanting the bridge rectifier version, so I decided to add the files needed for anyone who wants to go this route. I had to update the rectifier  because the original I used is now out of stock, with no expected re-stocking date. The new part is a little bigger so the board width had to increase slightly to just under 10mm. No big deal.

Note that the 1210 smd resistor will  need to be selected for the AC voltage you will be using, and should be about 1.4 times the value of the part shown in the original user notes in the OP. So for instance, if you are using 18VAC (instead of DC) and green leds @13ma, the value should be 1.2K x 1.4 = 1.68K; rounded up to 1.8K. Purchase this value in lieu of the 330 ohm shown in the BOM below.

The circuit is the same as shown five posts above. The board layout, 3D view, Digikey BOM and the gerbers are included below.

Note that the Digikey prices shown in the BOM are for lots of 10 each of the parts, and are Canadian dollars. US prices will be about 75% of these. Hope this helps for anyone wanting to go the rectifed AC route.
