@gunrunnerjohn posted:330 ohm resistors? That's not standard for the 5 meter reels with 300 of the 2835 LED chips, they use a 150 ohm resistor! If there's a 330 ohm resistor for each three LED group, I can't imagine it generating enough heat to melt plastic!
330 ohm resistors for the powered car end lights. The non powered cars just used LED strips.
