Can any of the PIAA and Nokya brand bulbs affect my headlight systems wiring?
Please read the FAQ immediately above also, which explains that as long as you choose the correct [stock] bulb wattage for your headlight system’s wiring harness (where you plug in the replacement bulb), everything should be fine. For example, the PIAA Super White H3 bulb comes as a 55W=85W model and an 85W=130W model. Most vehicles can safely accept only the first model, 55W=85W. The latter model is a high-wattage style with an actual wattage rating of 85W, which means your headlight system must be already set-up to accept this increased wattage.
