are most Honda/Acura Ballast universal?

for example TL and s2000?

 

I don't belive they mount to the headlamp the same way. Call a Acura dealer and compare the part #'s to be sure.

 

like stated above, they may mount differently but the ballast should be the same as far as connections go for the D2S bulbs. I dont think they would use different brand name ballasts with the honda/acuras. Should be the same but if not you might want to check the brand because they differ just a little between the philips and or hella ballast which I think are found in the Toyotas.
