Lol, no it doesn't it just makes them whiter, not brighter. It might look brighter but those bulbs use a blue film to produce a white light, this reduces overall output. Most of the aftermarket bulbs, including silvstars, are snake oil. A good OEM Philips bulb is going to be brighter than anything on the AM site, ppl just think that because its yellow its dim. The human eye actually sees best through yellow light, this is why OEM HIDs are 4300k and many
new auto manufacturers are putting yellow halogens in the fogs vs any sort of HID.
To answer the OP's question, whatever size bulb the projectors take, that is the HID bulb you want, they should plug into your existing ballasts. Also, shame on you for EVER running HIDs in stock reflector housings but kudos to finally doing something that will keep you from blinding incoming traffic. You will want a 4300k-5000k bulb btw. Anything over that will reduce visibility as the lumens start to fall off drastically after 5k and the human eye does not work well in blue light which is why all the "hyper blue" and whatever rice 8k+ HD bulbs are also snake oil and dangerous.
