HARD-TO-FIND PRODUCT: This small "mini" replacement bulb delivers an extraordinarily loud honk for its size. IMPORTANT: Reed screws into horn, not the bulb. So if your reed screws into bulb, then our bulb will not work (see photos). FITS THESE HORNS: This bulb fits "mini" vintage car, taxi, antique, old-brass and clown horns. Also fits Dobani bulb horn product code: BULBM. LARGE OR MINI: We offer bulbs in just two sizes: Large and Mini. Large is the "standard size" bulb and fits most bulb horns. The Mini is for little "bicycle-size" horns. NOTE: A Mini Bulb does not generate enough blast for standard size horns. So even if our Mini Bulb fits your standard size horn, you should find a bulb designed for your specific horn instead (prices typically start at $20.00), or retrofit Large Bulb. HOW TO CHOOSE BULB SIZE: 1. Measure Bulb Tube. If outside diameter is 11/16" (17.5 mm), then get Large bulb. If outside diameter is 5/8" (15.9 mm), then get Mini bulb (see note above). 2. Measure Brass Fitting. If horn fitting OD is 5/8" (15.9 mm), then get Large bulb (same as Large bulb tube ID). If horn fitting OD is ~9/16" (14.3 mm), then get Mini bulb (same as Mini bulb tube ID). 3. Measure Bulb. If bulb circumference is 11-1/2" (29.2 cm), or length from base to neck is 5-1/4" (13.3 cm), then get Large bulb. If bulb circumference is 8-3/16" (20.8 cm), or length from base to neck is 3-1/4" (8.2 cm), then get Mini bulb. WHY CHOOSE THIS BULB: If you want a brand new pre-tested budget-priced, antique-style, spare replacement bulb that fits your Mini Bulb Horn plus other smaller bicycle-size bulb horns, then this bulb is for you. TECHNICAL SPECS: Bulb Diameter: 2-3/4" (7 cm), Bulb Circumference: 8-3/16" (20.8 cm), Bulb Length to end of brass collar: 3-1/4" (8.2 cm), Brass Tube Length: 1-1/4" (3.2 cm) more or less, Brass Tube ID (screw fitting): 9/16" (14.3 mm) at 28 tpi (threads per inch), Brass Tube OD: 5/8" (15.9 mm). ## Product Details - **Brand:** Folkroots - **Item Weight:** 1.65 Pounds - **Mounting Type:** Handlebar Mount - **UPC:** 814362020022 ## Images ![SPARE "MINI" RUBBER BULB w/free mounting tips booklet & protectant - fits antique taxi, clown and bicycle-size horns - Image 1](https://m.media-amazon.com/images/I/718giujswlL.jpg) ![SPARE "MINI" RUBBER BULB w/free mounting tips booklet & protectant - fits antique taxi, clown and bicycle-size horns - Image 2](https://m.media-amazon.com/images/I/91dLFSGah3L.jpg) ![SPARE "MINI" RUBBER BULB w/free mounting tips booklet & protectant - fits antique taxi, clown and bicycle-size horns - Image 3](https://m.media-amazon.com/images/I/81cqj7PjrdL.jpg) ![SPARE "MINI" RUBBER BULB w/free mounting tips booklet & protectant - fits antique taxi, clown and bicycle-size horns - Image 4](https://m.media-amazon.com/images/I/810W+kiuaDL.jpg) ![SPARE "MINI" RUBBER BULB w/free mounting tips booklet & protectant - fits antique taxi, clown and bicycle-size horns - Image 5](https://m.media-amazon.com/images/I/81VDRGkABSL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐ 4.0 out of 5 stars Sizing *by R***N on Reviewed in the United States on August 3, 2021* After taping threads to make bulb screw on, it works great. ### ⭐⭐⭐⭐ 4.0 out of 5 stars Spare 'mini' rubber bulb fit and works as advertised. *by D***S on Reviewed in the United States on March 23, 2019* I satisfactorily replaced a decaying bulb for a horn in my collection. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Fit my 100 year old motorcycle horn perfectly.
