Hi,
Here is your solution.
Get two (2) 9LED - 39mm festoon globes.
also buy two (2) 50 ohm 10w resistors
(here is a good link,
http://www.radioshack.com/product/in...entPage=search)
(the picture is the wrong picture - but you want this item)
then just attach these resistors to the bulb tip "housing" which has the bulbs sitting in them.
You will get error free LED license plates use then
please let me know if it worked/not for you
