Yes - I'd already bought one of those and did the job today. Good to have a fit and forget set-up, it'd be just my luck to get hit by some wazzock on one of the occasions that I'd forget to turn it on. (I was hit three years ago, at first the driver was reasonable and co-operative but after a few days started lying and trying to deny the damage was her fault, luckily the guy behind me stopped and offered himself as a witness). I did consider Will_Gleaves' recommended solution but to be honest the Add a Fuse was just too simple.
