These C Light LED modules are circuit boards that fit right behind the factory diffusing reflector, illuminating in an extremely bright white, as well as a brilliant amber.

Time to upgrade your WRX or STi headlamps! These C-Light LED modules are circuit boards that fit right behind the factory diffusing reflector, illuminating in an extremely bright white, as well as a brilliant amber. Don't be fooled by other options on the market: these modules have been designed from the ground-up, and manufactured in St. Louis, Missouri, to be absolutely the brightest lights physically possible. They are compatible with all factory headlamps: WRX Base/Premium as well as WRX Limited and STi.

The custom-designed LED modules replace the factory bulb or single LED, illuminating with a much higher intensity. With our proprietary high-density "HDLED" technology, these modules are populated with over 500 LED chips, which are then coated by a diffusing gel, resulting in a perfectly uniform light when turned on. When it's off, the diffusing gel hides the chips, resulting in a clean, OEM appearance.

Manufactured in USA, the modules light in a pure 6000K white color, not a cool blue like cheaper products on the market. And because they use modern high-power amber chips, rather than traditional LEDs, the amber is even brighter than the white!

To power the modules efficiently, your order includes two custom-designed drivers, which feature transient voltage suppression, reverse protection, and a switching driver for extremely high reliability over time. And here's what really makes this product shine over the competition: with an embedded microcontroller, the drivers utilize multi-stage PWM dimming, to allow for a half-brightness white, for use at night (parking lights), as well as a full-power white, for use as DRL during the day. Finally, the amber is run at even higher power, making the turn signal easily visible in broad daylight!

SPECIFICATIONS
Total LEDs: 524 (262 per side)
Real LED Output Power: 13 watts Amber, 10 watts DRL, 5 watts parking (per side)
Inputs: Plug-and-play connector for ground and parking light. T-taps for DRL and turn signal.
Integrated Protection: Full waterproofing and shockproofing, transient suppression, overvoltage protection, thermal shutdown, reverse input protection.

Wiring instructions are included with your order. Using the included connectors, you will plug in the parking light connector, then tap turn signal and DRL signals, if you desire. We hope to release a plug-and-play wiring option in the next few weeks, which will be compatible with existing modules. You do not need to use resistors or a new flasher module with this product.

Professional installation is recommended, as the headlights must be opened. However, these lamps are substantially easier than most to work with, so we do recommend watching the installation process yourself, by viewing their video (to be released soon).

All Diode Dynamics products are backed by a 3-year replacement warranty.

NOTE:

If you do not have spare butyl sealant in hand, RetroRubber or other butyl sealant is REQUIRED. The OEM sealant cannot be reused! TRS RetroRubber can be stretched to the proper length and width to fit the headlight casing channel.

Adorable, Complete Set—Great for Special Occasions
Color: Beige, Size: 12, Color: Beige, Size: 12
This suit set is such a great find! It comes with everything you need—jacket, pants, shirt, tie, and bow tie—which makes getting a dressed-up look so easy. It's excellent quality for a suit in this price range. The linen fabric gives it a nice, lightweight feel and a polished look that works well for both formal and semi-casual events. My son looked adorable in it, and it was perfect for the spring wedding we attended. What I love: Complete 5-piece set—no need to buy extras Lightweight and comfortable material Classic, stylish look with nice details (lapel, pockets, etc.) Adjustable waistband is super helpful for fit Versatile for weddings, holidays, and other events Fit was true to size based on the chart, but I agree with the recommendation—if your child is between sizes or growing quickly, sizing up is a good idea. I sized up with the hopes that he can wear it again for another event because it looks fantastic! Overall, a really cute and practical suit set that looks great without being uncomfortable. Perfect for any special event

Boys’ 5‑Piece Linen Suit Set
Color: Beige, Size: 16, Color: Beige, Size: 16
I ordered this 5‑piece linen suit in size 16 in the beige color. The set includes the jacket, pants, dress shirt, bow tie, and a slip‑on tie. The outer fabric is a blend of 70% polyester, 25% linen, and 5% spandex, and the lining is 100% polyester. The material is lightweight, which works well for warm‑weather events, but the pants are noticeably thinner than the jacket. The jacket feels sturdier because of the full lining. The jacket has a peak lapel, flap pockets, and cuff buttons, and the stitching and seams are tight and even. I did notice a few loose threads, but the fabric itself was smooth with no tears or flaws. The pants have an adjustable waistband, which is helpful, but the length was too long and will need to be tailored. The overall cut of the suit seems designed for children on the thinner side. The shirt included in my set was a pleated style rather than a plain dress shirt. It wasn’t the style shown in the product photos, and I would have preferred a standard shirt that could be worn for various occasions rather than a very formal shirt. The tie is a pre‑tied slip‑on style with an elastic band. I would have preferred a traditional tie instead. The suit arrived in good condition with no damage, and the color was even throughout all pieces. The price is on the higher end for similar 5‑piece sets. I rated it 4 stars because the jacket is well made and the set includes all the expected pieces, but the thin pants, unexpected pleated shirt, and slip‑on tie kept it from being perfect.

Adorable and Well‑Made Outfit for Special Events
Color: Light Blue, Size: 10, Color: Light Blue, Size: 10
Got this suit set for my son and absolutely love it. It comes with everything he needs to look sharp, and I really appreciate that it includes both a tie and a bow tie so we can switch up the style depending on the occasion. The quality is impressive for the price — the fabric feels light and comfortable, and the whole outfit has a polished look without being stiff or uncomfortable. The fit was spot on, and the adjustable waistband is a huge help for getting it just right. My son looked great in it, and it’s definitely something he can wear for more than one event. The little details on the jacket and pants give it a classic, dressed‑up feel that works for weddings, holidays, or any special moment. Overall, it’s a stylish, practical set that makes getting him ready so much easier. Really happy with this purchase.

Boys linen fabric suit
Color: Light Green, Size: 16
Boys suit set in a lighter green color. This suit is made with good proportions and seems to fit well. The sizing seems slightly big so maybe size down one size. The fabric does wrinkle easily so be aware that sitting and folding the suit may cause wrinkling. Otherwise it is a very nice suit for a formal occasion. It comes in many good colors.
