finding a K5HL

I cant seem to find a K5HL other than http://realtrainhorns.net/shop/index.php?_a=product&product_id=156 if anyone has any connections if you could tell me that be great

Do you want a whole separate K5HL from you current K5, or do you want to change it?
Because you could sell your 3a, 4a, 5 and buy a 1L, 3, 4. They’re individually mounted aren’t they?

No I want to add a k5hl or a k3hl the more the merrier or anything other than what I have

You could save a little money (and room) and buy 1L, 3 and 4 individually and get fancy with some sort of relay system so you can flip a switch on your dash to toggle between 1,2,3a,4a,5 and 1L,2,3,4,5. This way you wont need to have two #2 and #5 bells under your truck.

I agree. You could do it electrically with individual solenoid valves for each bell. Then by flipping some switches, you could set which horns would blow.

If you don’t need to instantly switch between horns, you could put a ball valve on each bell. But you would have to crawl under there to switch horns.

My original plan was to do it electrically.
