It wants a damn good whipping !!!!
Sounds like your battery could be going a little soft.
If you start the motor and imediately reach for the gear selector and it triggers the lights, this is often a sign of a weakening main battery, that is not supplying sufficient volts to operate the autobox ECU.
Try this:
Start the engine before readying yourself for the road. Start the engine, put your seatbelt on, do your lippy, fârt and whatever else you do before driving off, then select the gear you want. This allows time for the battery to revive itself before supplying juice to operate the 'box ECU.
