    Question Small horn in engine bay

    I know the main horn for the CT is located in front of the radiator and they are LOUD. But I'm curious what looks like a small horn next to the engine is use for. I could not find a description or reference in the manual (unless I miss reading it).

    Here's a picture of the small horn I'm referring. Anyone know about this?
    Thanks.

    Probably not a horn... Interesting looking though. I've never opened my hood. Might be time to have a look.

    Edit: I thought pressure switch.. but now I think it is the Alarm Horn...

    Haha...found the answer to my own question.

    Searching the web I learn the small horn by the engine is referred as "Security Horn". It works in conjunction with the factory alarm feature.

    Why would Lexus put a small horn for alarm system? Wonder if a siren will work in it's place. Another mod idea?

    That's odd, I would have thought it just uses the normal horn for the alarm.

    Just a SWAG, but normal horn could probably easily be defeated by thief by pulling fuse; also might be higher, more piercing pitch.
