I just replaced position light bulb and need help resetting warning on dash.

 

The warning should go away by itself if the bulbs are working. Did you put in LED bulbs? That will cause problems with the warning system.

 

Just smack the offending light with your hand. Good chance that the bulb will light right up and the message will go away. The bulb holders don't do a great job with the bulbs they use in US spec cars. The bulbs loosen up and appear to be burned out.
