If you need auxiliary lights to help with the brightness, you should really switch back to the regular halogen bulbs, which will give you back the light on the road you need for safe driving.
I realize this message probably isn't getting through, but those fake "HID" bulbs you're using are illegal to have installed on a vehicle used on public roads, they are unsafe, as evidenced by the fact they aren't putting out enough light on the road where you need it, and they are also probably blinding everyone else on the road since they aren't the correct bulbs for the reflectors in a housing designed for halogen bulbs.
Is your life or that of other drivers on the road really worth the cosmetics of having fake "HID" bulbs in there or being able to make a fool of yourself by bragging that you have fake "HID" bulbs in your vehicle?
You're spending money on additional lights to fix a problem you have fabricated by putting in illegal, unsafe bulbs.
If you REALLY want HID lights, get some auxiliary HID fog/driving lights and mount those, and use some Sylvania Silverstar halogen bulbs to match the light color in the headlights if you must.
