Hey, they work. And they're real cheap at any auto parts store. These particular ones are 12-volt, 4-ohm, 4.9-watt license plate bulbs with matching sockets.
I have a set of MB Quart coxially-mounted separates that I have in my Solara with the Musicomp crossovers that utilize light bulb protection for the titanium tweeters. This particular set is older than my 2000 Solara and still work beautifully. I've never blown a tweeter nor one of the bulbs and they have been installed and have remained operational in two vehicles since I purchased them in the late 90's.
The science behind this is that when you start to drive your tweeters too hard, the bulbs begin to get brighter and brighter. As they do, they get hotter and hotter. What happens to a load in any electrical circuit as it gets hotter? It's resistance increases. Incandescent bulbs are designed to do that. There's your protection.
And it has the additional advantage of not affecting the tweeter phasing.
Don't try this with LED bulbs though, it won't work.
