<h3>About Diamond Group</h3><p>Diamond Group is a dedicated manufacturer of automotive lighting and electrical components, serving professional technicians and everyday drivers who need reliable, vehicle-ready solutions. Operating under the <strong>dg-usa.com</strong> brand identity, Diamond Group has built a focused catalog of over 100 products that covers the full spectrum of vehicle lighting — from exterior safety lights to interior illumination and the electrical accessories that keep them powered.</p><p>What sets Diamond Group apart is its commitment to purposeful product development. Rather than chasing breadth, the company has concentrated on the lighting and electrical categories where fit, finish, and regulatory compliance matter most. Whether you're restoring a classic vehicle, replacing a worn-out assembly, or stocking a shop with dependable replacement parts, Diamond Group products are engineered to meet OE specifications without unnecessary complexity.</p><h3>Exterior Lighting You Can Count On</h3><p>Diamond Group's exterior lighting lineup is anchored by its <a href="/10888-diamond-group-tail-light-2864">tail lights</a>, which are designed to deliver proper illumination, correct lens color, and mounting compatibility for the vehicles they serve. Tail light assemblies are among the most commonly replaced exterior components on any vehicle — whether due to accident damage, UV degradation, or simply the passage of time — and having a part that installs correctly the first time makes all the difference.</p><p>Complementing the tail light range, Diamond Group also produces <a href="/10888-diamond-group-side-marker-light-2824">side marker lights</a>, the often-overlooked but federally mandated visibility lights mounted on the sides of vehicles. These small but critical components help other drivers judge a vehicle's length and position in low-light or nighttime conditions, making them a genuine safety item rather than just a cosmetic detail.</p><h3>Bulbs for Every Application</h3><p>Beyond assemblies, Diamond Group supplies a versatile selection of <a href="/10888-diamond-group-light-bulbs-200615">light bulbs</a> to support both exterior and interior lighting needs. Their bulb lineup includes multi-purpose interior light bulbs that serve dome lights, map lights, cargo lights, and other cabin applications across a wide range of vehicle makes and models. Having the right replacement bulb on hand is one of the simplest and most cost-effective ways to keep a vehicle's lighting system in top shape.</p><h3>Electrical Parts &amp; Accessories</h3><p>Rounding out the Diamond Group catalog is a line of electrical parts and accessories that support proper installation and integration of lighting components. These products reflect the brand's understanding that a lighting part is only as good as the electrical connection supporting it — and that technicians and DIYers alike benefit from having the right supporting hardware available from the same trusted source.</p><h3>Why Choose Diamond Group?</h3><ul style="list-style:disc"><li>Focused expertise in automotive lighting and electrical components</li><li>Products designed to meet or match OE fitment and performance standards</li><li>Coverage spanning exterior assemblies, safety lights, bulbs, and electrical accessories</li><li>A streamlined catalog that makes it easy to find exactly what you need</li></ul><p>For drivers, fleet managers, and shop professionals who want dependable lighting replacements without guesswork, Diamond Group delivers a no-nonsense solution backed by real automotive engineering know-how.</p>

Product Details

The Diamond Group DG726121VP is a 39-diode LED tube bulb designed as a direct replacement for standard 12-inch T-5 fluorescent tubes in RVs and marine applications. This energy-efficient LED upgrade provides bright, reliable illumination while consuming less power than traditional fluorescent bulbs.

Key Features:

  • 39 high-output LED diodes for superior brightness
  • 12-inch T-5 tube size fits standard fixtures
  • Bipolar wiring design prevents incorrect installation
  • Quick-connect wiring ends for simple, fast installation
  • Direct wire connection to 12V DC power (ballast bypass required)
  • Includes 2 LED bulbs per package

This LED conversion eliminates the need for a ballast and provides instant-on operation with no warm-up time. The bipolar wiring configuration allows connection in either direction, making installation foolproof. Simply remove the existing fluorescent tube and ballast, connect the LED bulb directly to your 12V DC power supply, and enjoy long-lasting, energy-efficient lighting.
