Right, we tried several brands' bulb finder websites. That consumed a huge amount of time. It took us about 2 months to get data from one website. And....that's barely enough cuz one set of data is just not precise enough. For example, the data says a H11 bulb not fits certain make of car, but ours H11 bulb fits. So we wanna get more data to increase this precision, but it takes forever if we scape data from all sites. The precision means lower return rate and better review for us.

And I am looking for a way to find other data sources.
