Reading indicator/headlight status from CAN bus?
 

I'm doing a lighting project and I was wondering if anyone knew of a reference of available values from the CAN bus. In particular I'm looking for any of:

- brake light status
- Turn signal status
- Hazard light status
- Headlight status

Obviously I could just tap the wires themselves but reading off CAN would be a LOT easier.

bonus values that might be interesting:
- brake pedal pressure or braking force
- running lights status
- instrument cluster brightness
- current gear (A/T)
- A/T operating mode (D, D + paddles, M)

The following I'm pretty sure I can get easily as they're in the OBD spec, but any other info is aprreciated:
- engine rpm
- vehicle speed
- throttle position
- gas pedal position
