Solar house number light

Updated: 22 October 2026

You want the house number readable after dark, and the only lit plaques in this set are two K Smart Sign Exalted LED boards at £12.99. A solar house number light can make the digits visible at night. In England it also takes the sign out of the unlit Class 2A limit, and the seller does not guarantee the lamp from October to February. Unlit plaques stay on the [house number comparison](/hub/garden-decor/house-number). Garden solar lights elsewhere in this hub are a different product. Peter F. used the two amazon.co.uk listings and the England advertisement regulations. Another brand's claim of 8–10 hours is not copied onto these ASINs.

The two plaques in this set

B0CX1VLY44 is the matt grey plaque with a classic font. B0CX1VRR9S is the matt black plaque with a modern font. Both are £12.99. Both show 4.2 from 2,404 reviews, and the opening UK reviews use the same dates and wording. That is one sample. The black listing states an internal battery, snap-on fixings, 350 g, and 28 cm by 16 cm. The grey listing leaves the batteries question unanswered and disagrees with itself on size: 280 mm by 160 mm against 28 cm by 28 cm. Who should skip a lit plaque is on the best house number plaque page.

Winter and cloud

Solar performance is not guaranteed from October to February. The note cites about six hours of daylight and 18 hours of night, and it points to March to September as the better months. On the black listing the battery is internal and recharged by sunlight. Cloudy days leave it flat. The grey listing does not answer its own batteries question. Do not fill that gap from the black listing. One light stopped after a couple of months in bright sun. A north-facing porch is the case where this product is the wrong tool even in June.

How the light is held on

The plaque and the lamp are not fixed in the same way. The black bullets say snap-on fixings are provided for the sign. Reviews say the light is a separate piece on double-sided tape or a sticky pad, and that it falls off unless it is glued or screwed. The snap-on line is not a description of that pad. Fitting the board sits on the how to fit a house number page. If you drill for the plaque and then trust the pad for the lamp, you have followed the reviews' failure. The grey file does not list snap-on fixings. Outdoor, weatherproof, and batteries are unanswered questions on that listing, while recommended uses include exterior. That line is not a yes to the weatherproof question.

Illumination and Class 2A

Even a lamp that works is still illumination. In England, Class 2A covers an identification sign on the premises up to 0.3 square metres with no illumination. Every plaque measured in this set is under that area. The area is not the problem. The lamp is. The Planning Portal says an illuminated sign may need consent at any size. Scotland uses 0.2 square metres. If you want to stay inside the unlit class, use a porch light you already have and leave the plaque itself dark. The order of those checks is the house number buying guide.

Common questions

Do these two listings have separate review counts?
No. B0CX1VLY44 and B0CX1VRR9S both show 4.2 from 2,404 reviews, and the opening UK reviews match. Quote that sample once. The prices are both £12.99 in this capture. The bullet lists differ. Grey leaves the battery question unanswered. Black states an internal battery, snap-on plaque fixings, and a weight of 350 g.
Will the light work from October to February?
The listing says solar performance is not guaranteed in those months, and it describes about six hours of daylight against 18 hours of night. Best use on the note is March to September. That is the seller's caveat, not a lab graph. Reviews also include a lamp that stopped after a couple of months in bright sun, so a winter warning does not cover every failure in the sample.
Does the plaque need direct sun?
The black listing says the internal battery is charged by daylight, that you should place the panel in sun, and that cloudy days leave it flat. A long flat period can damage the battery. The grey listing does not answer its own batteries question. A shaded north wall is a poor match for either colourway if you need the lamp most nights.
Is a lit house number inside England's Class 2A?
No. Class 2A does not allow illumination. The 0.3 square metre cap is for an unlit identification sign, and these boards are under that area. The lamp still puts them outside the class. The Planning Portal says an illuminated sign may need consent at any size. A porch light that is not part of the sign is a different arrangement.
How is the lamp fixed, as opposed to the plaque?
Reviews say the lamp is a separate piece on a sticky pad or double-sided tape, and that it can fall off and crack. The black listing's snap-on fixings are described for the sign, not as a screw for that lamp. The grey listing does not state snap-on fixings at all. Drill the plaque from its stencil. Do not assume the lamp uses the same fixing.
What if I only need a number at night and the wall is in shade?
This pair is a weak answer. The black listing already says cloudy days and a lack of sun leave the battery flat. A deep porch or a north wall is that case for most of a British year. An existing porch light, or an unlit digit you can still read by that light, keeps the sign out of the illumination rule.
