Spare Rubber Bulb for Circular, Large, Small and Straight Horns
Fits virtually all the popular bulb horns...this is the low-cost bulb you've been looking for.
Just screw it on and start honkin'! (See tips below if bulb won't fit.)

Make that Old Horn Squawk Again!
Large replacement bulb delivers extraordinarily loud honk for Circular, Large, Small and Straight horns. (does not fit Double Bell or Mini horns).

Bulb measures a substantial 3-3/4 inches (9.5 cm) in diameter by 5-1/4 inches (13.3 cm) in length to end of brass collar. Total length to tip of brass tube is approximately 7-1/4 inches (18.4 cm) (varies). Designed for 3-part brass bulb horns (bulb-reed-horn). Spare brass reed available separately if needed.

Reed screws into horn, not the bulb. So if your reed screws into bulb, then our bulb will not work. (Yes, the reed slides inside bulb tube. But reed is physically attached to horn.)

How to Choose the Bulb Size you Need
Measure brass tube diameter. If outside diameter is 11/16 of an inch (1.75cm), then get this large bulb. If outside diameter is 5/8 of an inch (1.59cm), then get Mini bulb.

Buy with Confidence
Largest Bulb Seller on eBay, and Just About Everywhere Else

There's a good reason why so many shoppers order their bulbs and bulb horns from Bone Dry Music. Actually, there's at least three good reasons:
  1. You get comprehensive product info: We do our best to give you all the info and facts you need so there are no surprises when you open the box.
  2. We're easy to deal with: Got a problem with your order? We take care of you.
  3. You get a good deal: Go ahead and shop around. Our prices are about as good as it gets.
What's more, your order is expertly boxed and packed. And ships quick too—usually within one business day.

Don't Waste Good Money on Bad Bulbs
Beware of sellers shipping defective bulbs. If you search long and hard enough you might find a seller who offers these same bulbs a little cheaper than we do. But no other seller offers bulbs at a lower price that are inspected, pre-tested and fully guaranteed. In fact, last time we checked, no other seller tests their bulbs at all. They just grab any bulb out of the tub, dump it into a box with no padding—or worse, a flimsy envelope—and mail it off to you. And if you have a problem with the bulb? Good luck. But don't take our word for it. Check their reviews, testimonials (or lack thereof) and eBay or Amazon feedback for yourself.

Order Worry-free. Our Bulbs Work.
Our bulbs are pre-tested and fully guaranteed. We'll have your horn up and honking again before you know it. Can you afford to buy bulbs that don't work? Well, we can't. And in case you were wondering—yes, lots of sellers offer these very same bulbs at outrageously high prices. We don't understand why shoppers buy them. But they do. So why pay more for less? You deserve better. So don't waste your time and risk your money with shady sellers. Order now and discover why more than 1,541 smart eBay shoppers ordered guaranteed bulbs from Bone Dry Music.

Good Deal for Thrifty Shoppers...Satisfaction Guaranteed

These are rather excellent products for the price. But they ain't fancy high-class articles. Most of the bulbs are just fine and you can expect them to serve you well for at least a year or two, maybe more. But if the bulb you get does not meet with your satisfaction, then just let us know so we can make things right.

How to Generate a Loud Honk
Squeeze rubber bulb quickly and firmly. The horn should generate a loud blast. (If you squeeze rubber bulb gently, the horn will make no sound at all.)

Bulb won't fit your horn?
Bulb Mounting Tips

This large bulb fits most vintage bulb horns with no problem. Just screw on the bulb and start honking. But the screw fittings on some bulbs and horns are close—but don't quite match, and can be a little fussy.

If you need a rubber bulb like original equipment, then you will want to find a shop that specializes in vintage auto parts. Some of those shops offer premium priced reproduction car horn bulbs manufactured for your specific horn. Prices start at around twenty-five dollars. But if our bargain priced rubber bulb does not quite fit your horn and you want to save a little cash, below are tips from customers who describe a few easy ways the replacement bulb will make that old horn of yours squawk again.

Both Tubes Same Size, or No Threads?
If you want to attach the horn tube to the bulb tube, but they are both the same diameter (i.e. one will not fit inside the other), then try an inner sleeve splice. This surprisingly easy solution fastens both tubes using a tube within a tube. "Extremely simple—5/8" (15.9 mm) diameter nylon spacer fit inside the tubes like a glove," reports Alan in California adding, "nothing else was needed." Need to Splice Mini-Bulb Tube to horn tube? Try 9/16" (14.3 mm) diameter nylon spacer.

Bulb Tube Diameter Too Big?
This is the easiest fix for most situations. Try wrapping your horn threads with teflon tape. That's the stuff plumbers wrap around pipe threads to prevent leaks. If teflon tape won't work, then try electrical tape. But if tape won't work, then consider attaching the bulb permanently using epoxy putty, solder or other adhesive. A better alternative might be to remove the brass tube and replace it with your own, which is described below.

Install Horn Tube Directly into Plain Large Bulb
Try inserting the horn tube directly into our large Plain Bulb. Our plain bulb is a rubber bulb with no hardware (i.e. no brass collar and no brass tube). The Plain Bulb hole/shaft diameter is 5/8" (15.9 mm). Plain Bulb should work if your tube OD diameter is 11/16" (17.5 mm).

Install Horn Tube Directly into Plain Mini Bulb
The Plain Mini Bulb hole/shaft diameter is 1/2" (12.7 mm). Mini Bulb should work if your horn tube OD diameter is 1/2" to 5/8" (12.7 mm to 15.9 mm).

How to Convert Regular Bulb into a Plain Bulb in 2 Easy Steps:
If you already own one of our large or mini Spare Rubber Bulbs, feel free to swap it for a Plain Bulb. But if you want to save time, then you can convert your regular bulb into a plain bulb. How? It's easy. All you have to do is remove the brass collar and tube.

1. Remove Brass Collar
Remove brass collar using small screwdriver with 1/8" blade (e.g. shirt-pocket screwdriver). Carefully pry rim crimp open. Push up and outward. Lift collar off. Re-attach later or discard.

2. Remove Brass Tube
With the collar off, push screwdriver down between tube and rubber neck. Wiggle the tube and twist it out. Important: Be sure to twist metal tube clockwise. That's because the end of the tube inside the bulb is crimped with sharp fluted edges. The tube end might flare out and rip the rubber bulb hole/shaft when you remove it. So to prevent damaging the bulb, simply twist metal tube clockwise.

  • "I applied some oil on the old bulb threaded tube as well as the new, where it attaches to the rubber bulb," says a customer from Pennsylvania. "I was able to use the old tube in the new bulb. The first time I squeezed the bulb, my cat almost jumped through the ceiling. The horn works fine!!"
  • Oil helps remove bulb from tube. Let oil penetrate. Remove oil residue with rubbing alcohol after tube is extracted.
  • Apply a small amount of "thin" or penetrating oil at the tube/rubber neck. WD-40 oil has also been recommended. Clean off any residual oil or alcohol after removal.
  • "I was able to remove the tube in the bulb by cutting 4 slots and collapsing it, then was able to turn off," reports a customer from from Saint Louis. "My tube fit snug into the bulb, sounds great and will be a nice piece to hang on the garage wall."

How to Install Your Own Horn Tube into Plain Bulb (also in 2 easy steps):

1. Insert Horn Tube
Carefully insert (twist) your horn tube through bulb hole/shaft opening. Tube not snug enough? Then wrap end of tube with electrical tape to increase diameter. Or apply a little contact cement or superglue (cyanoacrylate) on tube to create a tight seal. Some customers insert a thin basswood shim to improve the fit. Tube slightly too wide for bulb? Then enlarge hole diameter with sandpaper or round metal file.

2. Re-attach Metal Collar if Desired
Position collar over tube and bulb neck. Use flat blade of small screwdriver, manual press, or other tool to compress collar rim firmly into bulb neck. If collar won't do it's job, then a ring collar might work if you have one that fits. If tube is secure enough without a collar, then you are probably good to go without one. But if tube is unstable—and if looks are not important, then trash the collar and secure the tube with a hose clamp instead.
