In respect to this item (1/24 Jetsonic Lightbar for Police Cars Product # CH17000 for $4.00) how do you (I) make it functional using LEDs and what size LEDs would it require. I am very new to this "hobby" and I am doing my homework prior to making purchases. I like the light bar but the introduction of the lighting would be a new feat for me. Suggestions or ideas? Thank you.jaschoener@verizon.net
