Review: Bright. - Just what I thought it would be. Perfect fit.
Review: Only slightly brighter than non-LED bulbs with filament - Replaced the trunk (boot) and map lights in my 2010 Mazda MX-5 Miata. Noticed a tiny spark when mounting the bulb to the trunk light, thought "oh ____" and sure enough, the vehicle would not start afterwards. Diagnosed that a 15A fuse had been blown, which I replaced in the engine compartment fuse box, dead car problem solved. So be sure to disconnect the trunk fixture from the vehicle electrical system before swapping bulbs. Concerning lighting performance, I found the new LED to be only slightly brighter than the OEM bulb. The lighting temperature (color of the light) was clearly much crisper and whiter, less warm, more pleasing and modern. The current draw is much lower than a filament bulb, but then again, trunk and map light aren't often used. Conclusion: Converting to this bulb is mostly aesthetic, do not expect a huge improvement in lumens output. You can also expect longer service life.

## Features

- Lights Dim Over Time, Replace In Pairs: Your lights are a pair, one is never turned on without the other. If one bulb burns out, the other isn't far behind.
- Instant Illumination: Unlike incandescent bulbs, LEDs illuminate immediately. This "instant-on" technology offers the added safety benefit of giving drivers around you more time to react.
- Superior Performance: Sylvania LEDs are manufactured with bright, long-lasting, SMD LED bulbs and a thermal management system that extends life and increases performance.
- May Require A Load Equalizer For Optimum Performance: To help prevent hyper flashing and bulb out warnings, it is suggested that a load equalizer or resistor be installed. See Sylvania's Load Equalizer product.
- The Sylvania Standard Of Quality: With over 100 years in business, Sylvania is the world leader in automotive lighting for Original Equipment Manufacturers (OEMs) and the aftermarket.
