Will this lamp fit my factory housing without any modifications?

Yes. These are designed as direct replacements for OEM license plate housings on the specified models. No drilling, cutting, or adapter brackets needed—it's a straight swap.

How much brighter is LED compared to the stock halogen lamp?

LED outputs significantly more light across the entire plate. You'll notice the difference immediately in night driving and low-light situations. The ice-white color also provides better clarity than yellowed halogen.

What's the lifespan difference between this LED and a standard halogen bulb?

LED lamps last thousands of hours longer than halogen. You won't be replacing this for years, whereas halogen bulbs typically need replacement every couple of seasons depending on use.
