Just 180? I googled the specs for the G450X and found 280! If it's only 180 then you really need to be careful which accessories to add. I had the idea to convert the H7 bulb to LED, but all H7 LED replacements have quite a massive heat sink, which for sure won't fit in the available space. There are only about 2...3cm between the current lamp socket and frame part that holds the front fairing. Did you replace the H7 bulb? What kind of replacement?
