I used Osram Hyperwhite (claimed +5000K) H7 bulb in my previous SAvvy.... stopped on several jpj and Polis traffic roadblock because they thought its pure HID... (have to admit, savvy headlight design and H7 bulb are the best from Proton).

However after pop up the hood and shown the bulb, they let me go (even one time got another savvy stopped and clearly they can see the difference in color temp of both car).
