These CPI Selective Yellow glass balloons clip onto any H4 bulb of up to 100/90w with a 25mm (1") base flange. This includes all Narva, CPI, and Philips bulbs, as well as many others. Just like the balloons crimped onto French-market H4 bulbs until 1993. These are re-usable; when your bulb burns out, you just transfer the balloon to the new replacement bulb. This balloon will not fit onto Osram H4 bulbs. Price is for one balloon. |
