matt the headlights are controlled by the computer and because the hids are only 35watts compared to the 55 of a halogn bulb, it see that there is not enough current and it shuts off the light and then cycles on and then off ect, therefore the flicker, there are a couple options, one you can run your power from tyhe parking lights, 2 you can by the resistors and make em yourself, i no when i had that truck the headlights were horrible, i tried every kind of bulb i could get , ended up leaving the blue ebay bulbs in it when i got rid of it, i had a set of 6 inch lights behind the grill, that solved my light issue . also hids wont work a daytime running lights, there is not enough current for them to light up, which is why many people wire them to the park lights.
if you are interested in a hid kit dont waste your money on a "brand name" kit, unlesss its from twiggy on dodgetalk, ddmtuning.com has great kits at unbeatable prices, i havent personally seem the h13's for the ram but my mazda hids are great and no issues.
