Durability was another important factor for me. I wanted headlights that would last and not require frequent replacements. I looked for information on the expected lifespan of different types of bulbs. My goal was to invest in a product that would provide long-term reliability without constant upkeep.
Price Range
Budget considerations were unavoidable. I set a price range for myself, understanding that quality often comes at a cost. I compared various options within my budget while keeping an eye on quality and features. This helped me balance my needs without overspending.
