My 2015 lexus es350 was crashed when I bought it. Anyhow I bought some used headlights without the ballast. I went to a shop and they installed some hid plug and play kit. So my question/ problem is what can I use to cover the hole where the ballast supposed to go? No one will sell me just the cover. I don't want to spend a lot of money on the whole ballast. Which u don't even need. Thank u
