Backup Alert Recommendation for a 2007 GMC Savana

Question:

Hello, I have a 2007 GMC Savanna, with a 3157 back-up bulb, will your 3156 work in on my vehicle?

While a 3156 can fit a 3157 socket it will not function properly. For a backup alert I recommend # RVS-W02. It can be mounted under the back of your 2007 GMC Savana on a horizontal or vertical surface. It taps into the reverse light wire on the vehicle and will create an audible alert when the vehicle is put in reverse.
