Great price, Great horns
Fitted both these bad boys in under 5 minutes on a 2013 Lexus IS 300h. Fits straight on using the existing bolts and even the power connector fits. 50 bucks each from Lexus parts, and these are the same and sound better. Get them !!!! you won't regret it at this price...Also fits Toyota as they use the same power connections

Good tone
Very quick to dispatch and the horns give a quality 'classy' tone which is plenty loud enough.

Sound great!
Got a new Toyota which came with a horn that would have made Noddy's sound impressive... These sound great and are taken seriously by other motorists when used! Easy to install

Much better than standard horn
Much better than a standard disc horn that was fitted from factory, wiring pluged straight in with the factory plug, 2 bolts to swap over and it was done. Hardest part was not breaking the clips for the engine bay covers. They sound much beefier than the original ones. I got them on an open box, so a bit cheaper, but even at full price, more than great value for money. If your Toyota / lexus ones have failed then definitely take this cheap easy upgrade rather than a universal one and fiddle around with little crimp connectors.

Vast improvement over the original Toyota horn
Installed in just a few minutes to my Corolla. The original horn is pathetic but these Hella trumpet horns are loud enough to be heard by all road users and pedestrians. Well worth the money.

Always loved hella brand horns. This is no exception. Proper manly horn compared to the stock soft beep. Surprisingly even cheaper than original alternative. Low price, better product. Buy it today my friend.
