Is there any way to increase the turn signal volume on a 2016 Accord? I have trouble hearing it.

There's no adjustment for turn signal volume. If it's working it's ok
No solution. Per my dealer, the muted sound (which I can't hear ) on my 2016 Civic is digital and intended to be that way by design. No more old world relay clicking. I find this non- sounding turn signal feature to be a flaw. I have a 2018 vehicle by another manufacture that has a digital turn signal sound which is at a volume that is audible over road noise; the way it should be... Honda needs to recall and fix their turn signal sound indicator. TDB

I ended up creating a little box that connects to the Accord F-CAN bus via the diagnostic port and sniffs for the turn signal codes and, when seen, puts out a sound that I can hear. Now I won't have to hear my wife say "your turn signals are on" ever again. The total cost of the box was less than $65 - well worth it in my book. A small mod to the program (I used an Arduino) would probably work on a Civic.
I don't have enough information (or knowledge) to make a box that identifies the turn signal code. Maybe, this type of box can be produced by an enterprising soul.
I appreciate each comment...it looks like a done deal...will have to be more visually alert, but thanks a whole lot Bart
Torino_3426, in case you're still following this tread, could you provide any more information about your project?. I'm trying to do something similar on my 2013 Accord, but I'm stuck on finding the Honda specific PID/code to get the turn signal status from OBD2. Any specific information that could provide would be greatly appreciated.

The turn signal info appears on the high speed CAN bus which is a differential bus on pins 6 and 14 on the OBD2 connector. The message id is 0x294 and the left signal is 0x20 in the first message byte and the right is 0x40, active high. The 0x294 codes come in at 40ms intervals so you'll have to remember when the signal goes high and when it goes low. There is a CAN bus decoder shield available for the Arduino which made life easier.
