If someone has questions about LEDs in general, just ask. I have created a few LED projects for my truck (new puddle lights in the doors using both a 24 and 18 LED array in each door and also a 780 (390 per) taillight mod). So, I understand the difference between the filament bulb ratings and LED ratings. I can also tell you roughly how many LEDs of a given MCD are needed to match up to a given wattage bulb.
As for the load balancing resistors that are required for LED bulbs, those resistors are going to pull about 20 watts of power (power = V2/resistance, or (14.4) squared / 10 ohms). So, yes, the resistor will be hot very fast. You can probably get away with say a 20 or 25 ohm resistor, which will dramatically drop the amount of power being turned to heat.

Think I repaired it... it's close to the original, but maybe a bit different. My head hurts.

Wow your post was missing quite a few things! That sucks...wonder what happened???
So it seems as though type f are the best of all of them eh? What were the prices on those? I've got a few bulbs on the mounty I'd like to replace. Can't remember did you get all yours from ebay or from vled?
Nice write-up btw!

Yah, it took me about 2 hours to replace all the pics and vids. i had saved the text previously though, so it wasn't all from memory.
Type F did work best in all applications, and wasn't expensive either. I think I paid $15 shipped for each pair from ebay. Sometimes, it is difficult to find either the amber or red ones...for some reason.
There is another one, similar to Type F, but instead of 3 leds on the end, it has 5. This will give a more symmetrical look to it, instead of a triangle/upside down triangle appearance. I recommend them highly. Here is a link for a set.
PS thanks for the comp on the writeup. I hope it helps someone someday.

Hey thermo, I have read that you need the larger resistors for the turn signals. Is there really any truth to that, or will the smaller ones work in all applications? I ask, becuase they are easier to find mounting points for.
