The Simplex 4903-9432 is basically the same as the 4903-9426 except in White. Not much history explaining since I mentioned a lot on my 9426 video. Please check that video out if you’ve haven’t seen it yet. Truealerts are really loud compared to the late 90’s Simplex Electronic Horns. Please do not this video if you have epilepsy. I hope you enjoy the test.
