You're right, they're not cheap. The problem is that if they're not being made any longer, they're cheaper than converting to sealed beams plus you stay original. I notice the same seller is still selling the chinese 2530s. Don't waste your money on them. He's also selling new 2330s and if they're the same chinese crap don't buy them either. If anyone's interested I have a few 2220s and a fair number of 2336 bulbs (the 12v equivalent to the 2330) for sale. Don's bulbs is selling the 2336s for $54 each.

I'll let mine go for $4 each.
