I would sugegst good quality LEDs
but if you still want to get HIDS just go to any decent decoration shop and get them 
90% of these HIDS in market are Chinese so it doesn't matter alot which ones you get , just make sure you get the ones with 6 months to 1 year warranty , and make sure shop keeper writes warranty on receipt.
Don't try to install them yourself the first time , these shop electricians can do it with their eyes closed because of experience what I would suggest is you observer carefully what they are doing , and how they are doing it.
