LED conversion difficulties

Hi to everybody.

Today I received new "wedge type" LED lights. They are Warm White and extremely
long shaped. I fitted one to the middle taillight and like to share the result
with you. There will hardly be any bigger LED wedge light bulb for the license
plate light. Its length fitted tight, without touching, and it's bound to stay
into place like in Hotel California. I ordered some similar Warm White LED bulbs
that are one row shorter for the dash. I will take and use whatever fits. The
Warm White is still a very cool white light but a little more red behind the red
lens then the cool white LED from the brake taillights, it is to be seen at some
of the pictures (slide-show at the above link) and I included a picture from
those LED's also. The brake lights work at 1/3 their power as taillights,
because the dots have three chips each. That is why it just looks like them not
being able of filling the lens with light at the corners, like the wedge type
does. I think this has a good effect in people instantly knowing that I am not

This is the link to the add of these wedge mini-towers (2X):\

The seller:
These the specifications:
For DC 12 Volts only
Current: 30mA
color: Warm white (3000-3500k)
Lumen: 35-40
Life time: more than 5,000 hours
The picture in the add reflects the sort of gray light they produce except it is
in fact rather blinding and without very noticeable dark spots in the corners. I
did put the red dot on the sides.

I do not have to worry about blackened wedge bulbs anymore. The former turned
noticeably black within a year. Greetings. Alfred

bulbs I found (and linked to in a previous post) save 4 watts per bulb (if you
believe the manufacturers). There are 11 bulbs of that style on a stock PC800.
That adds up to big savings fast if extra watts are what you're going for.

market weren't acceptable. They've improved quite a bit since then. In another
two years I bet they'll be even better. Have you looked around recently to see
what you can source domestically? There might be a better option that is red
for your tail lights. The ones I got for the brake lights were red. I had to
settle for a white T10 bulb for the tail light/license plate bulb though. Can't
have everything :-)

I bought them on e-bay.

lights with lots of white light shining downwards and red light up front. Do not
bather this bulb but replace it with a clean conventional one (they will turn
black on the inside long before they burn out). After-all an LED light is not
completely without load either and in only one such small bulb there is not a
lot to gain.
