can you bypass the cdi?
1. If you mean the light control module, then yes you can by-pass. It it being done by other s8 owners. However, I just installed a LED fog light on my Super 8.
I converted an H3 fog light to Super bright LED.
2. Yes, Some also install single HIDs and we call them "one eye jack" You can carry, not install, a spare battery in cases of emergencies. A smaller one will do.
3. Those wedge bulbs are park lights. U.S. version super 8s park lights don't operate because the headlights turn on automatically when you start the engine. Euro and Asian version have park light and headlight switches.
4. Those winkers are there to comply with the law. Check your laws if you can convert your winkers to the original ones.
