We are fairly new to the camping life. Our safe travels alert has been going off. For some reason early hours of the morning. I have read up and they say they should be replaced every 5 years our camper is a2013 model. Have no idea if it has been replaced before as warranty not completed by previous owner. Who should I get to replace it.?Should I buy first?

Pardon my ignorance but what is a "Safe travels alert" ?

I believe it to be the same as Engine warning light - Also get affected if non genuine service parts are used.
