About This Part
Low-tone horn (OE 13171428-00, alt HA-3721020A) for the BYD e2 and e2 Glory, 2019-2025. This unit supplies the deeper bass note that pairs with the high-tone horn to produce the car's two-tone signal. It arrives with its formed steel bracket and sealed two-pin plug and mounts to the original point in the engine bay. Choose it when the bass horn has become faint or dead, or when replacing both horns together to restore a clear, balanced blare.

Frequently Asked Questions: OE 13171428-00
What if the number on my old horn does not match this one?
If the number on your old horn does not match 13171428-00 or its alternative listing HA-3721020A, do not place the order on this listing yet. Use the quote route on this page and give the number exactly as it is stamped on the unit you are removing. This lets the number be checked properly before anything is sent out. Getting this step right avoids the wrong horn turning up at your door for a part that sits in the engine bay.
Will I need to wait long for this horn to turn up?
Delivery time is confirmed with your quote. When the parcel arrives, open it carefully and check the horn against the old one before you take it out to the car, since that is your chance to spot anything amiss while you can still act on it. Have the OE number 13171428-00 to hand for that comparison. If the numbers do not match, hold off fitting it and use the quote route on this page to sort it out first.
Where does the low-tone horn sit under the bonnet?
Have a look at the photographs on this page before you order, as they show the exact mounting position in the engine bay so you can compare it against where your old horn is bolted. This one is a metal horn finished in black, matched to OE number 13171428-00 for the BYD e2 and e2 Glory. Check the number stamped or printed on your old unit matches before fitting, since horns can look alike but sit on different brackets.
