Holley is clearly working towards cornering the market on reliable and convenient LED upgrades for classic cars. Their RetroBright headlights were a hit with customers, and we loved their period-correct look and performance. Now, Holley has released LED bulbs to upgrade your vintage car’s brakes, turn signals, and more with modern performance while also maintaining the classic look.

With their new LED bulbs that come in three different sizes, Holley is looking to meet the lighting needs of millions of classic car owners who are looking to improve their classic. Just like the universal-sized RetroBright LED headlights, these are designed to fit comfortably in a measure of different housing types.

ABOUT

Like an engine that does not leak, these RetroBright headlights from the folks at Holley are a long-awaited member of the classic car aftermarket scene. Lighting is often neglected on classic cars as existing replacements are often too big or do not match the styling of the car. Not to mention the fact that many replacements are hardly better than their OEM counterparts.

Holley has expanded their RetroBright line of classic car lighting products to include lighting components such as break lights, interior lights, and turn signals. The RetroBright LED bulb is a perfect combination of reliability, color, and performance that you can install on your vintage ride.

These LED bulbs are available in three different sizes: T10, 1156, and 1157. The 1156 is a single intensity and 1157 is the dual intensity bulb when it comes to output. These sizes will essentially cover all the common non-headlight applications for a classic car or truck.

Color

Holley is offering these bulbs in four different colors. They offer a bright white color, warm white, red, and amber. These color options should be able to cover all your vintage car’s lighting needs from turn signals and brake lights to interior and accessory lights.

Size

We mentioned the different bulb sizes earlier, but we wanted to briefly discuss the physical area that these bulbs take up. Holley based these bulbs in a traditional glass capsule, much like the stock incandescent bulbs. This prevents you from running into fitment issues that those large aftermarket LED bulbs can sometimes come in.

Holley knew how to package this bulb in a way that matches the size of your OEM part.

FLASHER RELAY

Companies like Holley live and breathe classic cars. It benefits them greatly to have such a background to inform their products and it is no different with the optional 12V flasher that you can purchase with the bulbs. You are likely to run into a hyper flash when installing these LED bulbs, so Holley has created this thermal flasher relay that can be easily installed into the existing relay connector.

CONCLUSION

We looked at the Holley Retrobright headlight a little while back, and we absolutely adored them. In fact, you can check out our full review of them here!

If you are looking to kit out your classic car or truck with the best possible lighting while also maintaining the look and feel of your vehicle, these Holley RetroBright LED bulbs are the way to go.
