A blister on the tire sidewall is a raised area that looks like a bubble or bulge on the outer surface of the tire. It is typically caused by the separation of the tire's inner layers, which can be a result of manufacturing defects, impact damage, or overinflation. A blister can weaken the tire's structure and increase the risk of a blowout, so it is important to replace the tire if a blister is detected. Driving on a tire with a blister can be dangerous and should be avoided. **

You can cut a small piece of the material and attach it to the sidewall using a strong adhesive. This will provide the necessary grip for you to repair the dynamo. Additionally, you can also use a rubber band or a piece of rubber tubing to wrap around the sidewall for better grip while repairing the dynamo. **

A semi-modular power supply falls in between, with some essential cables permanently attached and others that can be detached for flexibility. Each type has its own advantages and disadvantages depending on the user's needs and preferences. **
