The correct way to go is with higher wattage halogen bulbs. You may have to upgrade to a separate relay system to power them but it's the only way to go.
Any of the coloured, tinted, etc., lamps won't give the brightest light. The coating cuts the light output. The claims are for higher colour temperature, which is true, but they will NOT have more light output than a similar wattage, clear lamp.
I have spent years in television as a DOP cameraman which means lots of lighting. Matching a tungsten lamp to daylight means either filtering or dichroic in front of the lamp. Either way, there is less output from the lamp. An HMI TV lamp is the same as the HID in a car; a different method of creating the light with a colour temperature closer to daylight. They also come in different wattages.
All automotive halogen bulbs are available in stock 55 watt but many places sell 85, 100 and 130 watt versions. A 130 in a smaller plastic lensed housing might not work well but 100s are usually safe. Another good way of getting lots of light in an older car with quad, 5 3/4" round is to use a 100 watt aircraft landing light. Very popular up here with truckers looking out for moose at night.
The problem with retrofitting HIDs into halogen fixtures is filament focus. The replacement HID may fit into the socket, but the focus point of the filament is usually wrong. In a vehicle that's available with either type of lamp, the lamp housing and reflector will be different. Typically, an HID in a tungsten housing will be brighter, BUT ONLY RIGHT INFRONT OF THE CAR. The long range will usually be lost because of focus problems.
Put the money into a nice set of wheels.
