For the US market, ensure products comply with CPSIA and FCC regulations if they include electronic signaling. For the EU, CE marking and RoHS certification are mandatory to prove the absence of hazardous substances. Technically, verify the battery cycle life (ideally >500 charges) and the use of Lithium Polymer (Li-Po) batteries for better safety and heat resistance compared to standard Li-ion cells. Additionally, check for German StVZO compliance if exporting to Germany, as it regulates beam patterns to prevent blinding oncoming traffic.
