i'm guessing that there are two wires leading to the brakes if there are two intensities... you could just make alternating strings of LED's connect to each light. ie first row is brakes, second row is lights, third row is breakes, etc...

If you wanted ALL the led's on at one time for low and high brightness you could do something with a 555chip (google it, you'll find a billion sample circuits and kits to use a 555). You set it to a VERY HIGH frequency 50/50 square wave for lights and you set it to solid 'ON' for brakes.

Everything i do at work that requires a dual- (or multi-) intensity LED we will drive it with a solid voltage for high or a square wave of various duty % for various intensities.
