I recently installed these bulbs in my RV and was blown away by the brightness .They are the perfect replacement for any automotive bulb that fits the listed models (1156, 1141, 1003, 7506, BA15S). The illumination is clear and bright, making my RV feel safer and more ENJOYABLE to be in. The only downside is that they are slightly more expensive than other options on the market but the quality more than justifies the price. Overall, I highly recommend this product for anyone looking to upgrade tSee full review
