Narrative:

Starting the arrival into slc, we were at FL310 over rock springs. I misread the arrival radial and intercepted a more southwesterly radial. The controller noticed my error and gave me a 290 degree heading back toward the arrival corridor. There were no other aircraft in sight or on TCASII. A low light setting was the problem. Next time I will turn the light up when checking a chart or plate and have better attention to the route of flight.
