Toyota Yaris indicator bleeper

[Tigerrrr.......]

Hello.

My father has a 2007 Toyota Yaris.

He's 87 with poor hearing and doesn't hear the indicator when it's on.

Apart from being 87, his driving standard is very good.

Is there some device I can buy to increase the volume of the indicator?

Any advice appreciated.

Thanks.

As above. A couple of buzzers spliced in to the hazard switch and hidden behind the dash would be an easy way to do it

I've a 2007 Yaris, and agree its about the quietest indicator tick I've come across, so he's not deaf or anything
