What do I need to check. My srs light permanently 'on'

Hi your SRS stands for (Supplemental Restraint System) or Air Bag. If the light is staying on, then there is a problem with the system. Have this checked by a professional. Not a DIY repair

I have a 2003 honda civic 4 dr sedan.I have brake lights and left and rear signals but no tail lights or license plate light.
