The toledo has separate bulbs for the main beam and dipped so if you fit HIDs to your dipped beam you'll still have your standard main beam and vice versa. Still works as before just will look very yellow compared to the HIDs.
The bulb warning device is only needed for newer cars like the
Mk2 Leon and Mk3 Toledo so as long as you have a 99-04 Toledo you'll be fine with a 'basic' set of HIDs.
Nowt wrong with the Hong Kong Cheapos either, I got mine from Diane-
shop and had no probs with them as did others from here.
