This mod is for the new Avalon owners! Because the new Avalon HID's lights adjusted way too low!
Hi black phantom this is for u as u requested and for few avvy owners as they asked me! And I hope it helps

It's very easy to do all you need is a 10mm O type spanner for easy access to rotate the bolt

Now as the pictures below shows the 2 bolts that must be adjusted as clockwise.
The best time to do this mod is in the night and u shall park your car ahead of white wall and 15 leg feet away :roflmao:
WARNNING: DONT ADJUST IT TOOO HIGH U'LL BLIND THE INCOMING DRIVIERS AND TEST IT WITH ANOTHER CAR AND READJUST IF IT'S TOO HIGH!
Mine works like a champ and when I tested mine they looked like if they're adjusted too high but its not! When u drives the test car you'll know what I mean! Just adjust it to your desired position

cheers and happy chillin :p
