    I'm new to AAC and very appreciative that this site is on the web. Thank You.
    I've been searching the web for a circuit to auto dim a string of 15 led's. I must be typing the wrong key words or something.

    Here is my dilemma.
    I want to install a 15 led string(amber) on my motorcycle as running lights.
    I would like the led's to be bright during the day, and dim at night automatically. A gradual dimming would be great and adjustable low dim point.

    The extra led's will increase my visibility on the road and are not for show

    I'm just learning about transistors and pretty good at soldering.
    I'm only on the 4th experiment in my 300 in 1 electronics kit.

    Thank you now for any help available. Les
