Expert Reply:

Your 2003 GMC Savana should use a 3157 bulb and not a 3156 like # HM20101VA. The 2 bulbs fit the same receptacle but the 3157 is a dual filament. For a backup alert that will work properly you can use # Surface Mount Back-up Alarm # BK97DB. It will mount underneath your van and wire into a reverse light wire. This backup alert at 97 decibels will be louder than the bulb type.

I have linked a video showing an example installation for you.
