Review: The requirements of most people are paradoxical. They want the brightest which also last the longest - as also economical! That does not happen! If you want still brighter, go for the GE Nighthawk Sport or Sylvania Silverstar - they are slightly brighter, but have shorter life-spans. [Only HID will be really brighter with longer lifespans. But then you will need custom builds - no ready-made kits are available for H4666 replacements. And LED is still not available except as fancy trims.] BRIGHTNESS: If you had really old lamps, these will appear really brighter. Otherwise marginally so. I find them as bright as those of neighboring new cars (except the premium ones). SPREAD: The spread is much better to the sides (specially to the right) than OEM, and also slightly further ahead. LONGEVITY: The extrapolated longevity is twice that of OEM and Silverstar - but only time will tell. The lens is glass and will not become hazy. The brightness of headlight is really dependent on several factors: (1) lamp itself. Older filaments gradually become thinner and offer greater resistance thus smaller currents. (2) reflector reflectance. As they become old, they lose their reflectance, and should be replaced every 5 years or so. (3) lens transparency. (never use ammonia-containing "glass" cleaners on car lens - they make plastic hazy). OEM Wagner was plastic - this is glass. (4) Fuse. Old fuses have increased resistance and they supply reduced voltage to the headlamps - these should be periodically replaced (some use higher rating fuses to get better light - NOT recommended). The advantage of sealed beams is - all first three items are replaced together (if possible, have the headlamp fuse also replaced with a fresh one). ## Features - Waterproof ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000CO7AJ8 | | Additional Features | Waterproof | | Auto Part Position | Right | | Brand | Sylvania | | Brand Name | Sylvania | | Compatible with Vehicle Type | Truck | | Country of Origin | USA | | Customer Reviews | 4.3 out of 5 stars 136 Reviews | | Global Trade Identification Number | 00046135310843 | | Is Assembly Required | No | | Item Dimensions | 16.5 x 12.7 x 10.2 Centimeters | | Item Weight | 1.32 Pounds | | Lens Colour | clear | | Light Source | Halogen | | Light Source Type | Halogen | | Manufacturer | sylvania | | Manufacturer Part Number | H4666XV.BX | | Model | H4666XV.BX | | OEM Equivalent Part Number | H4666XV.BX | | Special Feature | Waterproof | | Specific Uses For Product | Head Lights | | UPC | 046135310843 | | Unit Count | 1.0 Count | | Vehicle Service Type | Truck | | Voltage | 10.00 | | Wattage | 55 Watts | ## Product Details - **Brand:** Sylvania - **Light Source Type:** Halogen - **Special Feature:** Waterproof - **Specific Uses For Product:** Head Lights - **Vehicle Service Type:** Truck ## Images ![SYLVANIA H4666 XtraVision Halogen Sealed Beam Headlight 100x165 - Image 1](https://m.media-amazon.com/images/I/31kF9IlL+fL.jpg) ![SYLVANIA H4666 XtraVision Halogen Sealed Beam Headlight 100x165 - Image 2](https://m.media-amazon.com/images/I/410hH0cAZWL.jpg) ![SYLVANIA H4666 XtraVision Halogen Sealed Beam Headlight 100x165 - Image 3](https://m.media-amazon.com/images/I/415ZLuWeuvL.jpg) ![SYLVANIA H4666 XtraVision Halogen Sealed Beam Headlight 100x165 - Image 4](https://m.media-amazon.com/images/I/41HJ0CJ3ApL.jpg) ![SYLVANIA H4666 XtraVision Halogen Sealed Beam Headlight 100x165 - Image 5](https://m.media-amazon.com/images/I/41kvkvAJoPL.jpg) ## Questions & Answers **Q: Does these headlights have short prongs for that is what i'm looking for there for there myers plow lights** A: Fitment and application details for this bulb are dependent on the year, make, and model of vehicle it is being installed in. We suggest you may want to contact Sylvania directly at 1-800-729-3777 for assistance with your specific installation. **Q: Will it fit my 1995 Chevy S10.** A: Yes, the H4666 headlight fits the 1995 Chevy S10. **Q: Will this bulb fit into a flip-up headlight on my 1994 Ford Probe?** A: The size appears the same - I am not sure about the mounting. These H4666 lamps do not have any mounting mechanism included - the mounting mechanism must be present in the car for them to fit. **Q: Does this fit a 97 Chevy S10 ?** A: Yes, the H4666 headlight fits the 1997 Chevy S10 with sealed beam headlamps. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by H***R on 7 January 2026* Nice and bright. ### ⭐⭐⭐⭐⭐ Review *by D***E on 3 February 2014* The requirements of most people are paradoxical.

I was a little irritated about replacing lights that were still working. However, when you can see your turn signals reflection off of the roadway at night better than you can see the headlight's reflection, it is time. The difference was actually unbelievable. I do not understand the comments that say that they can tell no difference, because in my case the ability to see at night has been restored. As an added side benefit, the look of the truck has been greatly enhanced by the clear, bright looking, glass lights vs the old plastic OEM headlights that I had watched yellow over time. ## Frequently Bought Together - SYLVANIA - H4666 XtraVision Sealed Beam Headlight - Halogen Headlight Replacement 100x165 Delivers More Downroad Visibility (Contains 1 Bulb) - ACDelco 19313317 Crankcase Ventilation (PCV) Valve - Dorman 59207: Throttle Return Spring Assortment --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/801837334-sylvania-h4666-xtravision-halogen-sealed-beam-headlight-100x165](https://www.desertcart.tn/products/801837334-sylvania-h4666-xtravision-halogen-sealed-beam-headlight-100x165) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-04*
